Step 1 — Remove plastic trim on center console

Open center console
Remove silver trim in front of center console

Step 2 — Remove screws in front of center console

Remove 2X T-20 screws in front of center console

Step 3 — Remove console panel

Un-clip and set aside console panel below radio screen

**Step 4 — Remove radio

**

Un-screw 2X T-20 screws on brackets in upper corners of radio
Screws do not need to be fully removed. When the screws are unscrewed enough, the brackets will release
Once brackets are released, pull out and set aside radio deck

Step 5 — Remove plastic on left side of radio cavity

On the left side of the radio cavity there is a plastic grill. A small piece of plastic must be cut out of this grill to create a large enough opening for the EIS (electronic ignition switch) to be removed through.

Step 6 — Remove EIS from dash

Pull out push to start button and set aside (the push button is a cap that can be removed)
Un-clip the EIS (electronic ignition switch) from the dash and pull through radio cavity

Note: there are tabs on the top and bottom of the EIS. The EIS un-clips from the dash by squeezing those tabs toward the center of the EIS and pulling towards the front of the vehicle.

Step 7 — Un-plug harnessing from EIS

Un-latch 40 pin connector plugged into back of EIS by pressing locking tab above grey latch and pushing latch up
Un-plug connector from EIS

This is the harness that will be used to install the T-harness of the SKSNG205D4 to the EIS

Step 8 — EIS jumper modification

A jumper must be installed on the ignition switch in order to complete this installation. The jumper is a pin and a wire that is soldered on to the board of the switch (see pictures for solder points for pin and wire). To the left there are pictures of the modification.

Detailed installation instructions for EIS jumper and pin installation here: SKSNG205D4 & SKSNG222D4 EIS Jumper & Pin Installation Instructions

To properly install the EIS jumper, you MUST have a temperature controlled soldering iron.

If you would like to have the jumper installed by Mid City, you can send it to us and we will perform the modification for free (with the purchase of an SKSNG205D4). Please call 312-421-1114 ext. 1 or email sales@midcityengineering.com

Step 9 — Replace white 40 pin shell on EIS harness with provided black shell

The 40 pin connector that was removed from the EIS in step 7 has a white shell and 2X 20 pin inserts (black and grey). The 20 pin inserts need to be removed. The SKSNG205D4 comes with a 40 pin black shell. The 20 pin inserts will be inserted into the provided black 40 pin shell.

Some OEM connectors will not this connector swap. If the plugs match, you can move on to step 12

Using a pick tool, carefully remove the grey and black 20 pin insert connectors from the white 40 pin factory connector
Insert the grey and black 20 pin insert connectors into the provided black 40 pin shell

Be sure to place the 20 pin inserts into the provided connector in the same orientation as they were in the factory connector. It is advised that you take a picture of the factory connector before you remove the shell so that you can check the orientation after you have replaced the shell.

Step 10 — Insert 20 pin connectors from T-harness into the factory shell

One side of the T-harness provided with the SKSNG205D4 has 2X 20 pin inserts (black and grey) that look like the factory inserts used in step 9. The connectors are to be inserted into the white 40 pin shell that was removed from the factory harnessing in step 9

Insert the grey 20 pin connector from the T-harness into the white 40 pin factory shell – being sure to insert in the same side as the factory connector (compare to black 40 pin shell from previous step)
Insert the black 20 pin connector from the T-harness into the white 40 pin factory shell being sure to insert in the same side as the factory connector (compare to black 40 pin shell from previous step)

**Step 11 — Re-install EIS into dash

**

Route EIS back through left side of radio cavity
Clip EIS back into dash

**Step 12 — Plug white 40 pin shell into rear of EIS

**

Plug 40 pin white shell (now installed on T-harness) into back of EIS where it was removed previously and secure latch.

Be sure to check that connector is fully plugged in and latched to EIS

BEFORE MOVING TO NEXT STEP, MAKE SURE THAT MAIN CONNECTOR OF T-HARNESS IS CONNECTED TO SKSNG205D4 MODULE

Step 13 — ATTENTION: DO NOT PERFORM THIS STEP OUT OF ORDER. Connect black 40 pin shell to T-harness

The factory (chassis side) harnessing with the factory grey and black 20 pin inserts should now be inserted in the provided black 40 pin shell

DO NOT MAKE THIS CONNECTION UNTIL THE WHITE 40 PIN SHELL IS CONNECTED TO THE BACK OF THE EIS AND SKSNG205D4 MODULE IS PLUGGED INTO MAIN HARNESS

Connect 40 pin shell and chassis side harnessing into black 40 pin connector on SKSNG205D4 Tharness

**Step 14 — Remove front plastic sill cover on passenger side

**

There are 2X connections that need to be made under the passenger side floor (front) at 2X different CAN distribution blocks (rows of connectors).

Remove plastic sill cover along door sill plate and set aside

Step 15 — Pull back carpet

Pull back carpet in front of seat to access under floor area

Step 16 — Open access panel and locate distribution block

Open the black panel beneath the carpet along the door sill
Locate distribution block with blue and blue/white factory wires
Un-clip the block so that plugs can be access easily

Step 17 — Connect blue and blue/white plug to distribution block

The SKSNG205D4 has a small Tharness with blue and blue/white wires and white plugs. This Tharness will be used to make the connections at this block

Plug the plug end of the T-harness (side without the exposed pins) into any empty spot on the block with blue and blue/white wires

Step 18 — Insert key into EIS

There is a test using the LEDs on the SKSNG205D4 module that will instruct as to which factory plug will be removed from the block and connected to the other end of the blue and blue/white T-harness. To begin this test, you must have the module and T-harness installed behind the EIS and the key inserted but not turned.

Insert key into EIS and do not turn
Once key is inserted into EIS, the yellow LED on the SKSNG205D4 module should flash. Confirm the yellow LED is flashing and you are ready to begin the test.

Step 19 — Perform CAN plug finder test

To find which CAN plug should be removed from the block and connected to the other end of the blue and blue/white T-harness, you will remove each plug one at a time and connect to the T-harness.

When a plug is removed, the yellow LED will turn off- and when the correct plug is connected to the harness, the green LED on the SKSNG205D4 module will turn on and begin to flash.

Using a pick tool, unlock the tab on the side of the first connector in the block and remove from block. When a connector is removed from the block, the yellow LED on the module will turn off
Connect the removed factory connector to the T-harness (the side with the exposed pins)- being sure that the plugs are connected in the same orientation and the factory blue and blue/white wires are going to the blue and blue/white wires of the T-harness
After plug is connected to the Tharness, check the LEDs on the module. If the LEDs stay off, move on to the next plug
It may take up to 10 seconds for the LED to respond to each newly connected plug
Continue test until you find the plug that makes the green light on the SKSNG205D4 module turn on
Once you have found the correct plug, leave it connected to the Tharness.

Step 20 — Insulate connection and replace distribution block

Tape connection made between factory plug from block and Tharness connector and find secure location in wire channel along door sill for those connectors
Re-install distribution block into location in wire channel

Step 21 — Locate distribution block for Keyless Go connection

The SKSNG205D4 comes with a Keyless Go extension cable (20 foot brown and brown/red harness). The white connector plugs into 2 pin connector on SKSNG205D4 module labeled ‘KG.’ The other end of the harness is connected at distribution block with brown and brown/red wires on passenger side floor, along door sill, towards the kick panel.

Connection at the distribution block involves locating the correct plug using a short test, de-pinning the factory 2 pin connector and pinning the factory brown and brown/red wires into the provided adapter plug. The adapter plug plugs into the provided KG harness and allows the factory wires to bypass the block and connect to SKSNG205D4 module.

The distribution block with brown and brown/red wires is located in an access panel along the door sill, towards front of the vehicle in relation to the block used in the previous steps
Open access panel and locate distribution block with brown and brown/red wires along door sill, towards the kick
Un-clip the block so that the wires can be accessed

**Step 22 — Enter Keyless Go test

**

The SKSNG205D4 comes with a Keyless Go extension cable (20 foot brown and brown/red harness). The white connector plugs into 2 pin connector on SKSNG205D4 module labeled ‘KG.’ The other end of the harness is connected at distribution block with brown and brown/red wires on passenger side floor, along door sill, towards the kick panel.

Connection at the distribution block involves locating the correct plug using a short test, de-pinning the factory 2 pin connector and pinning the factory brown and brown/red wires into the provided adapter plug. The adapter plug plugs into the provided KG harness and allows the factory wires to bypass the block and connect to SKSNG205D4 module.

The distribution block with brown and brown/red wires is located in an access panel along the door sill, towards front of the vehicle in relation to the block used in the previous steps
Open access panel and locate distribution block with brown and brown/red wires along door sill, towards the kick
Un-clip the block so that the wires can be accessed

Step 22 — Enter Keyless Go test

To find the correct KG plug from the distribution block, you will use the LEDs on the SKSNG205D4 module.

Insert key in ignition and turn to first position (ACC)
Once in ACC, the yellow LED on the SKSNG205D4 module will flash
Once the yellow LED on the module is flashing, you are in the KG test

Step 23 — Perform KG test

To find the KG CAN plug, you will un-plug the connectors from the distribution block with brown and brown/red wires one at a time and observing the LED on the SKSNG205D4 module. When the KG connector is un-plugged, the yellow LED on the SKSNG205D4 module will shut off.

There may be two connectors in the block that cause the yellow LED to turn off. Please test each plug in the block. If there are 2 plugs that cause the yellow LED to shut off, you can confirm you have the correct plug by checking to see if A) when un-plugged, the radio can still be turned on and B) the push to start button will not start vehicle.

Using a pick tool, disconnect one factory connector from the distribution block with brown and brown/red wires
After un-plugging first connector, observe behavior of yellow LED on the SKSNG205D4 module.
If, after un-plugging the connector, the green LED shuts off- move on to next step. If the yellow LED does not shut off, plug that connector back into the block and remove the next plug from the block- repeat until you find the plug that, when un-plugged, causes the yellow LED on the SKSNG205D4 module to shut off

It may take up to 10 seconds for the LED to respond to each newly connected plug

When the KG connector is found (the one which, when un-plugged, causes the yellow LED on the SKSNG205D4 module to shut off)- move on to the next step

Turn key to off position and remove from ignition before making connections in next step

Step 24 — Connect Keyless Go harness

Once the KG plug is located (from the test in the previous step), remove key. The factory brown and brown/red wires from that block will be de-pinned from the factory connector and pinned into the adapter plug in the end of the provided KG harness (being sure to connect brown to brown and brown/red to brown/red)- factory wires will bypass block.

Using a pick tool, carefully de-pin factory wires from KG plug one at a time
Plug empty factory plug back into block so that the original plug can be used if system is un-installed
Pin factory brown/red wire into pin position 1 of adapter plug that is plugged into the end of the provided KG harness
Pin factory brown wire into pin position 2 of provided adapter plug

When pinning factory wires into adapter plug, note their position in relation to the provided KG harness. When the adapter plug is plugged into the KG harness, the factory brown wire will connect to brown wire of the KG harness and the factory brown/red wire will connect to the brown/red wire of KG harness

Connect adapter plug with factory wires pinned in the correct positions to the end of the provided KG harness

After harness is connected, the factory wires will be bypassing the block and instead going into provided KG harness (brown connected to brown and brown/red connected to brown/red)

Step 25 — Connect Keyless Go harness to module

Run KG harness to SKSNG205D4 module
Connect 2 pin white plug from KG harness to 2 pin white plug on SKSNG205D4 module labeled ‘KG’ (next to 20 pin main harness plug)

Step 26 — Check KG connection

Once the KG harness is connected to the SKSNG205D4 module, you should have the factory wires that were located using the KG test bypassing the block and running through the KG harness and into the SKSNG205D4 module. You can check this connection and confirm that the correct wires are connected by performing a quick test

Insert key in ignition and turn to the first position
Observe LEDs on SKSNG205D4 module. With the key in the first position and the KG harness connected to the factory wires, the green LED on the module should flash.
If the green LED is flashing, remove key from ignition and move onto the next step. If the green LED is not flashing, remove key from ignition and return to previous steps to check KG connection and/or redo KG finder test

Step 27 — Key box installation

An extra key needs to be installed with the system. The box for the extra key is included with every SKSNG205D4

Inside the provided key box is a battery emulator. The battery will be removed from the extra key being used for the installation and the emulator is inserted in place of the battery.

Remove key battery
Insert battery emulator in place of battery in the key with arrow on emulator labelled ‘FRONT OF KEY’ pointing towards the TIP end of the key

Step 28 — Connect key box to SKSNG205D4 module

Connect white plug from provided key box to 2 pin white plug labeled ‘KEY’ on SKSNG205D4 module

Step 29 — Test remote start operation

Insert push button back into ignition

Be sure that hood is closed and the vehicle is in a safe place to start. Vehicle should not remote start if the hood is open (parking lights will flash 7X)

The remote start will not work unless the push button is in the ignition switch

From outside vehicle, press PANIC button on key fob 1X (short press)

If the OEM key fob does not have a PANIC button, the SKSNG205D4 will automatically revert to a ‘LOCK

UNLOCK-LOCK’ remote start sequence

If vehicle does not remote start, the parking lights and yellow LED on the module should flash a series of times. The # of flashes corresponds to a failure code. The most common failure code is 9 flashes.

If you see 9 flash error code, attempt remote start while sitting inside vehicle with key. If the vehicle remote starts while sitting inside the vehicle with the key, check key box connection and operation of extra key installed in box. If vehicle does not remote start while sitting inside with key, check KG connection and EIS jumper modification

Step 30 — Test key takeover

While vehicle is remote started, test key takeover by entering vehicle with the key on you (for vehicles with Keyless Go locking and unlocking from door handle, this feature will work during remote start- if lock/unlock does not work from the door handle, check KG connections)
Once inside vehicle, press the brake pedal and the push to start button at the same time
If the key is present, the parking lights will flash 3X to confirm key takeover
Once key takeover is done, confirm that vehicle will shift into gear

Step 31 — OPTIONAL CONNECTIONS

The SKSNG205D4 is compatible with several add-ons and accessories. All accessories plug into labeled connectors on SKSNG205D4 module.

Compustar Drone: to connect Compustar Drone telematics module, plug grey 4 pin plug from Drone into 4 pin black plug labeled ‘DRONE’ on SKSNG205D4 module
Compustar RF remotes: Click here for instructions
Compustar DAS sensor: 4 pin plug cable from Compustar DAS sensor into 4 pin red plug labeled ‘SENSOR’ on SKSNG205D4 module. DASII or DASIII sensors can be used and will monitor shock, tilt, and vehicle movement and interface with the OEM alarm
Directed Smart Start: plug white 3 pin ESP plug on Smart Start into white 3 pin plug labeled ‘SMART START’ on SKSNG205D4 module. If Directed RF remotes are not being used, power for Smart Start can be connected by using the 4 pin white plug labeled ‘D2D’ on the SKSNG205D4 module.

If power for the Smart Start is connected through the D2D port, the white and blue wires on the Smart Start 4 pin MUST be disconnected

If D2D plug is being used to connect an XL202 (for adding Directed RF remotes), hardwire connect power and ground for Smart Start to the main T-harness.

Do NOT ground grey wire for Smart Start

Step 32 — OPTIONAL CONNECTIONS CONTD.

Directed RF remotes: to add Directed remotes, a Directed XL202 RF to data converter must be used. Connect the XL202 to the 4 pin white plug labeled ‘D2D’ on the SKSNG205D4 module. Connect Directed RF antenna to XL202 and follow XL202 programming instructions
Compustar CM7000: an external alarm can be added using a Compustar CM7000 (or equivalent). To connect alarm, use an RS232 cable. Plug one end of RS232 cable into black port on CM7000 and other end of RS232 cable into black 4 pin port labeled ‘DRONE’ on SKSNG205D4 module

RS232 cable must have blue and white (RX and TX) wires reversed on one end of the cable. For example, if blue wire is in the outside pin position on one connector, it must be in the inside pin on the other side of the cable.

Connect power, ground, and ignition wire from low current harness of CM7000. Constant power and ground can be wired to the SKSNG205D4 T-harness
