twofiftysx Posted March 3, 2009 Author Report Share Posted March 3, 2009 Yea its the positive wire that leads into the reverse light on the back of the car. Wow lol obviously. I was asking for the location under the dash. I think I found it. Green wire in the harness to the left of the steering column. Quote Link to post Share on other sites
smoofers Posted March 20, 2009 Report Share Posted March 20, 2009 It is a light green wire in the box (with a black cover and plastic nut) that sits just left of the break pedal. No need to catch the wires all the way at the back of the truck. Quote Link to post Share on other sites
