What make/model did you get? I've been looking into one of those aftermarket ones myself.
on my 07 silverado there is a stud on the front of the fuze box under the hood. i just bought a fuze for the stud and hooked up the wire to the stud and u have a fuzed wire. ill try to get a pic tomorrow if my explanation doesnt make sence.Your wiring may be similar to mine (2008 Silverado.) You will see modular plugs just above and to the left of the spare tire. Trace the wires running to a rear tail light. I chose the driver's side.
The correct wire to splice into was the green wire. The yellow wire goes to the turn signals, and the brown one is for the brakes. I grounded the black wire to the frame rather than splicing another wire.
I just put it in today, and still haven't found the correct hot wire from the fuse box. I plan to use the accessory lighter adapter until I figure it out. Maybe someone else can chime in with that info.
I have a Tahoe so the spare tire is under the chasis. The license plate is on the back door which lifts up. I don't think they are the same. But thanks for the post!on my 07 silverado there is a stud on the front of the fuze box under the hood. i just bought a fuze for the stud and hooked up the wire to the stud and u have a fuzed wire. ill try to get a pic tomorrow if my explanation doesnt make sence.
