NOTICE: If installing an ACTIVE tow kit, the vehicle must be programmed before trailer lights will function, see notice on Page 3.

NOTICE: Installation of Stealth products may or may not require the addition of a wiring harness to the vehicle.

  • The Rack Receiver only product does not require adding a wiring harness.
  • The Rack Receiver plus Tow Kit requires the addition a wiring harness that is compatible with the vehicle’s wiring. Depending on the vehicle, the harness will be one of two types, “Active” or “Passive.” The wiring section of the instructions will indicate which wiring harness style is being used and how to install it.
  • The Active Harness plugs into the vehicle’s wiring so that the vehicle’s computer can communicate with the trailer wiring. This allows certain functions such as cameras or backup alarms to continue to operate as designed. Some active harnesses require reprogramming of the vehicle’s computer before the trailer wiring is functional. For BMW vehicles that need programming, Stealth provides this service remotely. Refer to the Active Harness section of the instructions to determine if programming is required for this install. This programming must be taken into account when planning the timing of the Stealth product install. The remote BMW programming needs to be scheduled approximately 1 week in advance.
  • The Passive Harness is independent of the vehicle’s computer and communication system. The module of the harness is powered directly from the battery rather than the vehicle’s wiring harness. The module monitors the output signals from the vehicle’s lights. It then powers and activates the trailer lighting accordingly.

INSTALLATION NOTE: In most instances, these instructions will only outline disassembly of vehicle components.
Re-installation of components will require the installer to retain vehicle hardware and work through disassembly instructions in reverse order. When installation is complete, double check that all vehicle components have been replaced and are secured.

    FINAL VEHICLE EXAMINATION

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

  35. 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.STEALTH-HITCHES-SHR31019-Rack-Receiver-Kit-fig67

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.
