ADDITIONAL TOOLS FOR ACTIVE TOW KIT:

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. 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. Vehicles that require reprogramming need to be programmed at a dealership. 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 programming needs to be scheduled with a dealer in advance.

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.
