1. 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 7-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

2. On the driver side of the vehicle locate and remove the indicated rubber grommet. Drill a 3/8” hole in the grommet. Place the wiring harness control module inside the driver side cargo compartment. Feed the output wires and control module power wire through grommet from inside of the vehicle to the outside. Replace the grommet.

3. The wires on the input side of the wiring module need to be attached to the vehicle wiring. 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 and remove the sheathing. Use a clamp-on connector to connect the green wire to the right turn signal wire, behind taillight. (See reference table on next page.)

   • NOTE: Vehicles may have different wire colors than those shown. Verify circuits (wire colors) with multimeter.

4. 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 on next page.)
   NOTE: If two colors are listed, the first color is the dominant color.

5. Locate the ground stud in the rear driver-side cargo area. Trim white ground wire so it will reach the stud without excess wire. Crimp supplied fork terminal to the ground wire with a crimping tool. Loosen the ground stud and secure the fork to the terminal.

   • NOTICE: Loosen ground stud just enough to install fork terminal, so vehicle wiring does not lose ground.

6. The power wire will need to be routed to the engine compartment where it will connect to the battery. Route the wire from the grommet to the gravel guard on the passenger side undercarriage. Loosen the (4) nuts holding the gravel guard to allow routing through it. Then pass the wire up into the engine compartment.

7. Locate the fuse holder supplied in the wiring kit box. Remove the fuse from the fuse holder. Crimp the fuse holder lead to the black power wire. Place the ring terminal on top of the positive battery stud (+). Use provided M8 nut to connect.
   NOTE: Do not loosen the battery stud nut, just add M8 nut on top of ring terminal.

8. Determine the amount of power wire needed to reach the control module inside the vehicle. Trim the control module power wire to remove excess length. Use the included butt connector to crimp the power wire leading from the power supply to the control module power wire.

   • NOTICE (OPTIONAL): The butt splice connector is a heat shrink connector. Apply heat to waterproof the connectors after crimping.
     WIRE 7-WAY PLUG

9. Locate the 7-way housing. Use a screwdriver to loosen (2) screws. Remove 7-way round terminal block. Use a screwdriver to loosen the set screw at the bottom of the 7-way housing. Route output side wires of the wiring harness through the 7-way housing.
   Please follow instructions below very carefully. Incorrect wiring of the 7-way receptacle causes the vast majority of wiring problems.

10. Locate the slot keyway. Starting from the keyway going clockwise, attach the wires as follows:

    • Blue
    • Green
    • Black
    • Brown
    • Yellow
    • White
    • Purple (middle)
    • NOTICE: Markings on the receptacle may not match the correct wire configuration. Please disregard and follow the instruction above.
      TEST 7-WAY HARNESS WIRING

11. Put the 7-way receptacle back together. While everything is still accessible, you should test the wiring to make sure everything is connected properly and in working order. Replace the 20 Amp fuse into the fuse holder located near the battery.
    NOTE: Taillights will need to be temporarily plugged in during testing.

    • Start by connecting the multimeter negative probe to the ground blade on the 7-way receptacle.
    • Next, connect the multimeter positive probe to the power blade on the 7-way receptacle and check for 12 volts.
    • Once that is confirmed, move the positive probe to the left turn blade on the 7-way receptacle and check for 12 volts when the vehicle left turn blinker is active. You should see it pulse.
    • Next, move the positive probe to the right turn blade and check for 12 volts when the right turn blinker is active. You should see it pulse.
    • Next, move the positive probe to the marker/taillights. With the vehicle lights on you should see 12 volts constant.
    • Lastly, with the brake depressed, move the positive probe to the left turn blade where you should see 12 volts constant. Move the probe to the right turn blade where you should also see 12 volts of constant.

12. Carefully pass the wire of the 7-way housing through the mounting bracket. Attach the 7-way housing to the Stealth hitch frame as shown. Secure harness to Stealth hitch frame with cable ties provided in the wiring kit.

13. Secure all wires and wiring components. Use the remaining wiring kit 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.

14. Use the provided adhesive foam strips to secure the control module to an inside body panel. Use silicone to waterproof grommet.
    CUT ACCESS TO LATCH BLOCK

15. 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.

16. Use a Dremel tool to cut out fascia, as shown. The access hole size necessary varies depending on which kit you are installing. Follow indicated template. Use a file to smooth out the cut.
    NOTE: Make sure the hands-free trunk release cable is removed before cutting.

17. Reattach the hands-free trunk release cable using the (6) supplied cable tie mounts and 8” cable ties. Secure the cable to the rear fascia as shown. Trim the cable ties when finished.

18. Reattach and secure the fascia and other vehicle components in reverse order. Refer to Steps 1-18.
    NOTE: If your vehicle is equipped with antenna, carefully route the antenna wires unplugged in Step 17 back into the vehicle before completely re- installing the fascia.

19. The finished, under vehicle view.
    FINAL VEHICLE EXAMINATION

20. Examine the body panels to ensure that they are in a pre-installation condition. Test the electronic functions of the vehicle. Correct any inconsistencies.

21. 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.)
    • Prepare latching mechanism. Turn handle clockwise if needed.
    • Firmly insert “post” of accessory into latch block until handle releases indicating that the accessory is latched.
    • 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.
    • Use key to release safety locking pin.
    • 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 the latching mechanism. Turn the handle clockwise if needed.
2. Firmly insert the “post” of the accessory into the latch block until the 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 a 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.
