IF INSTALLING A RACK RECEIVER KIT, SKIP TO STEP 31. IF INSTALLING A TOW KIT, CONTINUE TO STEP 16.

INSTALL 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.
  

• Remove the trunk floor panel by lifting it up and out. Place the panel on blanket or safe area.

Use a 90 degree pick tool to open the cargo anchor cover (red arrow). Use a Torx to remove the cargo anchor. Use a socket to remove (1) plastic nut (green arrow).
  

• Locate the emergency trunk release handle. Remove the pull cable from the handle, then slide the cable through the hole into the area behind the panel. Dislodge the passenger side panel and pull it open to gain access to the area behind the panel. Retrieve the control module from the wiring kit box. Secure the control module to the floor of the passenger side cargo compartment with the supplied adhesive foam strips.
  

• Locate rubber wiring harness grommet on the passenger side of the vehicle. Drill a 3/8 “ hole in the grommet. Make sure to drill through grommet only and not to damage harness.
  NOTICE: Confirm that there is nothing inside vehicle behind grommet that can be damaged.

• Feed the wires and black sheathing of the 4-way plug through the grommet from outside of the vehicle to the inside of the vehicle.

• 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.
  

• 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.

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

• Locate the ground stud inside the passenger side cargo compartment. Trim the white ground wire so it will reach the stud without excess wire. Crimp the supplied fork terminal to the ground wire with a crimping tool. Loosen the ground stud and secure the fork to the stud.
  NOTICE: Loosen ground stud just enough to install fork terminal, so vehicle wiring does not lose ground.
  

• Locate the fuse holder supplied in the wiring kit box. Remove the fuse from fuse holder. Trim black power wire so it will reach the positive battery terminal (+) without excess. Crimp fuse holder lead to power wire. Connect fuse ring terminal to the positive battery terminal (+) using the provided M8 nut.
  

• Reinstall the 20 Amp fuse in the fuse holder. Test the 4-way plug using a multimeter or connect the plug to a trailer and verify that the lights and brakes work correctly.

• Use silicone to waterproof the grommet with the 3/8” hole drilled through it.

• Secure all wires and wiring components. 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

• Use a cutting tool to cut the gravel guard along the factory gap as shown in the image.
  

REINSTALL VEHICLE COMPONENTS

• Reattach and secure the fascia, underbody panels and other vehicle components in reverse order. Refer to Steps 1-7.
