InCarTec 29-UC-050-CHR2 Chrysler Steering Wheel Control Interface
Product Information
The 29-UC-050-CHR2 Chrysler Steering Wheel Control Interface is a device designed to allow easy integration of an aftermarket head-unit into certain Chrysler, Dodge, and Jeep vehicles. Compatible models include the Chrysler 300C (11-15), Grand Voyager (08-16), Dodge Caliber (06-12), Nitro (06-12), Journey (09-18), Jeep Cherokee (08-18), Compass (11-17), Patriot (11-16), Grand Cherokee (08-13), and Wrangler (07-17) models that do not have an OEM Alpine amplifier. The interface box comes with a set of cables that connect to the car and to the aftermarket head-unit, as well as a patch lead that connects to the 4 pole black connector on the control box. The interface box uses the CANbus system to communicate with the car’s steering wheel controls, handbrake output, illumination output, 12V ignition output, 12V permanent input, SWC ground output, reverse 12V output, and speed pulse output. The PCB inside the interface box has jumpers that can be set to suit most vehicles, but may need to be changed if fitting an Alpine head unit.
Product Usage Instructions
- Connect the cables to the interface box and to the car, and the patch lead to the 4 pole black connector (this is attached to pins 4, 8 and 12 of the control box). Connect the two 8 pin ISO connectors and the patch lead to the aftermarket head-unit. When connected to the car the interface will automatically recognise the vehicle. The green LED on the interface will repeatedly flash once followed by a pause. If the LED flashes red it may be necessary to swap the CAN wires, some vehicles have the CANbus wires reversed. Bullet connections are inline on the green (2) and white (9) CAN wires for this purpose.
- You need to set the interface to the brand of head unit you are fitting. The number of flashes between pauses corresponds to the make of head unit, see the table below for the number of flashes needed for each one. Press the VOL + and VOL – buttons on the cars steering wheel to increase or decrease the number of flashes. When you have the correct number of flashes, press SEEK+ to confirm and the LED will go to a solid green.
- If fitting a Chinese or resistive programming head-unit, set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now press the reset button 5 times, the interface will start to flash yellow (this allows prolonged pressure on the steering controls). Using the radio’s resistive learning menu, you can now learn and memorize the buttons. Wait at least 5 seconds between each button press. When finished, turn the ignition off and on, and the LED will go back to solid green.
- To reprogram the interface for another head unit brand or if the light is solid green before you have had the chance to set the head-unit brand, push the reset button in and keep it pushed in for 10 seconds, and then release the button. At this point, the LED should start to flash green.
- If fitting an Alpine head unit, set jumper J1 on the PCB inside the interface box.

Connect the cables
Connect the cables to the interface box and to the car, and the patch lead to the 4 pole black connector (this is attached to pins 4, 8 and 12 of the control box). Connect the two 8 pin ISO connectors and the patch lead to the aftermarket head-unit. When connected to the car the interface will automatically recognise the vehicle. The green LED on the interface will repeatedly flash once followed by a pause. If the LED flashes red it may be necessary to swap the CAN wires, some vehicles have the CANbus wires reversed. Bullet connections are inline on the green (2) and white (9) CAN wires for this purpose.
FITTING
You need to set the interface to the brand of head unit you are fitting. The number of flashes between pauses corresponds to the make of head unit, see the table below for the number of flashes needed for each one. Press the VOL + and VOL – buttons on the cars steering wheel to increase or decrease the number of flashes. When you have the correct number of flashes, press SEEK+ to confirm and the LED will go to a solid green.
For Chinese and resistive programming head-units.
Set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now
press the reset button 5 times, the interface will start to flash yellow (
this allows prolonged pressure on the steering controls ). Using the radios
resistive learning menu you can now learn and memorize the buttons. Wait at
least 5 seconds between each button press. When finished turn the ignition off
and on and the LED will go back to solid green. To reprogram the interface for
another head unit brand or if the light is solid green before you have had the
chance to set the head-unit brand. Push the reset button in and keep it pushed
in for 10 seconds and then release the button. At this point the LED should
start to flash green.
| Number of flashes | Make of head unit |
|---|---|
| 1 | Clarion 3.5mm jack |
| 2 | Kenwood 1 wire |
| 3 | JVC 1 wire |
| 4 | Alpine 3.5mm |
| 6 | Pioneer 3.5mm jack |
Resistive 2 wire Resistive 3.5mm jack
7| Sony 3.5mm jack
Setting the Jumpers
The Jumpers are on the PCB inside the interface box. By default they are set up to suit most vehicles and should usually only need to be changed if fitting an Alpine head unit. The jumpers are set by moving them between positions 1 and 2 or positions 2 and 3.
| Position 1-2 | Position 2-3 | |
|---|---|---|
| J1 | Alpine | All other Radio Manufacturers |
| J2 | Negative Handbrake (not all vehicles) | |
| J3 | Positive Reverse Output | |
| J4 | ||
| J5 | CANbus Handling |
The Reverse and Speed Pulse cables.
The reverse output (blue wire) is only needed when fitting a reverse camera to
the new head unit. The grey speed pulse wire is needed when fitting head units
with built in satellite navigation and some Kenwoods. If not required these
can be insulated and ignored.
The speaker adapter (brown ISO connectors)
If you are not getting phone or navigation audio through the front speakers, add this extra cable to swap the audio output from back to front. This is most often required on cars with original Boston Audio system.
Make sure the patch lead is connected to the 4 pin plug on the interface and the input on the new head unit. 29-UCCAB patch lead wiring information – shown from wire entry side of connector:
Chrysler 300C (11-15) Grand Voyager (08-16)
Dodge Caliber (06-12), Nitro (06-12) Journey (09-18)
Jeep Cherokee (08-18) Compass (11-17) Patriot (11-16) Grand Cherokee
(08-13) Wrangler (07-17)
NOT SUITABLE FOR WRANGLER WITH OEM ALPINE AMPLIFIER
