where is the reverse light wire under the dash?there is the blue wire coming from the back but I dont know which wire to hook it up to.

and I cant find the brake light wire coming from the back of the truck.

Im running w/o them now and need them hooked up b4 I get pulled over.

the brake light wire is hooked up to a plastic peace that is attached to the brake petal by metal prong. when released the metal and break petal breaks apart making the brake light come on.. as for the reverse light i have no idea cause i never had a problem with that. good luck!

the brake light would be on the brake light switch. If you wanna tie into them together, look at the bulk head on the firewall.

you will really need a wiring diagram, unless you wanna follow it from th eback up to the bulkhead.

I cant remember if they are like s10's or not, but if they are, firewall side is 2 wiring harnesses plugged into the main.. 1 is strictly fuel pump, taillights, reverse and brakes. that is a place to do it there too.

I removed all of the original wiring (except for the switches under the dash that are part of the column).

I have my brake lights figured out (they run off of the same wire as the turn signals (the wire from the rear of the truck) and two white wires (1 off of the brake pedal harness and another off of the turn signal harness).

The reverse light is ran from the transmission.

thanks guys
