IF INSTALLING A RACK RECEIVER KIT, SKIP TO STEP 27. IF INSTALLING A TOW KIT, CONTINUE TO STEP 14.

INSTALL PASSIVE WIRING KIT

Locate the wiring kit box. Review the contents of the box against the list above to check for missing components. The passive wiring kit uses a control module to manage the functions of the trailer lighting. The module has an “input” side that receives power from the vehicle’s battery and signals from the vehicle’s taillights. The “output” side of the module delivers this information to the 4-way plug. The control module is connected to the vehicle’s battery and taillight wiring as outlined in the next steps.

NOTICE: Do not allow electrical system to become disconnected from power or ground. Doing so may interrupt electrical systems

1. Locate and remove rubber grommet from the driver side of the rear wall. Drill a 3/8” hole in the center of the grommet. Retrieve the 4-way connector harness. Pass the grommet over the wires so the plug will be on the outside of the vehicle. Thread the end of the wires into the hole and replace the grommet.

2. On the driver side of the vehicle, locate the tail of the 4-way connector wire and the output side wires of the control module. Attach each similar color wire to each other using a red butt connector and crimping tool.
   NOTICE (OPTIONAL): The butt connectors are heat shrink connectors. Apply heat to waterproof the connectors after crimping.

3. Secure harness to Stealth hitch frame with cable ties. Maintain an 18” loop from the cable tie to the 4-way plug. Add the magnetic cable holder and secure to the harness close to the 4-way plug, with a cable tie.

4. The wires on the input side of the module need to be attached to the vehicle wiring. Inside the driver side cargo compartment locate the indicated part of the vehicle wiring harness. Use clamp-on connectors to connect the brown and yellow wires to wires behind taillight. (As shown in reference table below.)
   NOTE: Vehicles may have different wire colors than those shown. Verify circuits (wire colors) with multimeter.

5. Use an existing vehicle wire harness as a guide to route the green input wire to the passenger side of the vehicle. Locate the indicated part of the vehicle wiring harness. Use a clamp-on connector to connect the green wire to right turn signal wire behind the taillight. (As shown in reference table below.)

NOTICE: Do not connect the red brake wire. This vehicle does not utilize a separate brake circuit. The brake signal is sent down the left and right turn circuits simultaneously.

NOTE: If two colors are listed, the first color is the dominant color.

• Remove spare tire to get access to the battery. Turn knob counterclockwise.

• Locate the fork terminal supplied in the wiring kit box. Trim white ground wire so it will reach negative battery terminal (-) without excess wire. Crimp the fork terminal to the ground wire. Connect the ground wire to the negative battery terminal (-).

• Locate the fuse holder supplied in the wiring kit box. Remove the fuse from fuse holder. Trim excess power wire length. Crimp fuse holder lead to power wire. Connect fuse holder ring terminal to the positive battery terminal (+).
  NOTICE: Loosen battery terminals just enough to install wiring, so vehicle wiring does not lose ground or power.

• Retrieve the adhesive foam strips from the wiring kit box. Secure the control module to a body panel inside the driver side cargo compartment.

• Reinstall the 20 Amp fuse in the harness fuse holder located near the battery.

• Test the 4-way plug using a multimeter or connect the plug to a trailer and verify that the lights and brakes work correctly.

• Secure all wires and wiring components. Replace the grommet removed earlier on the rear driver side of the vehicle. Use silicone to waterproof the grommet. Use the remaining cable ties to secure wiring so that it is not loose and will not interfere with replacement of the fascia. Wiring should not be visible once the vehicle is reassembled.

CUT ACCESS TO LATCH BLOCK

• Detach the hands-free trunk release cable, from rear fascia.
  NOTE: Make sure not to damage the cable during the removal of the cable and the fascia cut.

• Use a Dremel tool to cut out fascia, as shown. Use a file to smooth out the cut.
  NOTE: Make sure the hands-free trunk release cable is removed before cutting.

• Reattach the hands-free trunk release cable using the (6) supplied cable tie mounts and cable ties. Secure the cable to the rear fascia as shown. Trim the cable ties when finished.

REINSTALL VEHICLE COMPONENTS

Reattach and secure the fascia, taillights, and other vehicle components in reverse order. Refer to Steps 1-10.

FINAL VEHICLE EXAMINATION

• Examine the body panels to ensure that they are in a pre-installation condition. Test the electronic functions of the vehicle. Correct any inconsistencies.
• Ensure that hitch components work properly.
  • Verify that the lock works correctly. Push in the safety lock on the latch block then unlock with key. The lock should slide back out with the key when unlocked.
  • Verify that each accessory can be installed correctly. Use the following steps to install and remove each accessory that will be used with the hitch. (Rack Receiver and Ball Mount if purchased.)
  1. Prepare latching mechanism. Turn handle clockwise if needed.
  2. Firmly insert “post” of accessory into latch block until handle releases indicating that the accessory is latched.
  3. Push in the safety locking pin until it fully engages. The locking pin prevents the handle from turning when pushed in, and confirms that the block is securely latched onto the accessory. The safety locking pin will not depress if the accessory is not fully latched.
  4. Use key to release safety locking pin.
  5. While holding on to the accessory, rotate handle clockwise to release and remove the accessory.
  • Verify that no part of the accessories come into contact with the body of the vehicle.

PRODUCT USE AND MAINTENANCE

NOTICE: If the hitch is being installed by a professional, the installer is responsible for training the end user in the use and maintenance of the product.

Accessory installation procedure:

1. Prepare latching mechanism. Turn handle clockwise if needed.
2. Firmly insert “post” of accessory into latch block until handle spins counter-clockwise indicating that the accessory is latched.
3. Always depress the safety locking pin and check that it has fully engaged.
   • Never use any accessory with the safety lock disengaged. Until the safety locking pin is engaged, the handle is able to turn. A fully engaged safety locking pin is confirmation that the accessory is properly latched into the latch block.
   • Never use the rack receiver for towing. The rack receiver accessory is only to be used with payload carrying products, such as bike racks or luggage racks.
   • Before each use, give the post of the accessory a light coating of lithium based grease.
   • Before each use, inspect the hitch to ensure that all bolted connections are secure and that no cracks or damage are present. Do not tow with the hitch if cracks or damage outside of normal wear is found.
   • Remove the Stealth accessories from the latch block after each use. Do not leave accessories plugged in for extended periods of time.
