Use a screwdriver to loosen the set screw at the bottom of the 7way 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.

21. 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.

22. The wires on the input side of the wiring module need to be attached to the vehicle wiring. Inside the passenger side compartment, use clamp-on connectors to connect the green, brown, and red wires to wires behind taillight. (See reference table on next page.)
    NOTICE: on 2022+ vehicles two brown wires may be present. Use the wires in the indicated row. The larger brown wire in the other row is a ground wire.
    NOTE: Vehicles may have different wire colors than those shown. Verify circuits (wire colors) with multimeter.

23. Use an existing vehicle wire harness as a guide to route the yellow input wire to the driver side of the vehicle. Locate the indicated part of the vehicle wiring harness.
    Use a clamp-on connector to connect the yellow wire to leftturn signal wire behind the taillight. (As shown in reference table on the next page.)

TEST 7-WAY HARNESS WIRING

26. 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. • 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 constant.
    MOUNT 7-WAY HARNESS WIRING

27. Attach the mounting bracket and 7-way housing to the Stealth hitch frame as shown. Secure harness to Stealth hitch frame with cable ties.

28. 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. Reinstall grommet and use silicone to waterproof it.

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

30. 2014-2021 vehicles: Cut out the fascia with Dremel tool. As shown in the two images with yellow text. Use a file to smooth out the cut.
    NOTE: The access hole necessary is different for the rack receiver and tow kits. Follow correct template.• 2022+ vehicles: Cut out the fascia with Dremel tool. As shown in the two images with green text. Use a file to smooth out the cut. NOTE: The access hole necessary is different for the rack receiver and tow kits. Follow correct template.

FINAL VEHICLE EXAMINATION

33. Examine the body panels to ensure that they are in a pre-installation condition. Test the lectronic functions of the vehicle. Correct any inconsistencies.
34. 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 counterclockwise 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.
