We elected to mount the wireless module beneath the rear seat in Paul's Boss 302. After removing the seat, Grant finds a key-activated, 12-Volt source in a wiring harness that runs from the trunk to the front of the car, and then uses a supplied tap to join the module's red wire with a power source. After securing the black wire to a good ground, the wireless module is wedged just below the rear-quarter interior panel, and the seat is replaced. The white wire on the module is its antenna. Once activated, the wireless system has a range of 100 feet.
