I picked up a new truck cap,with a discount...the discount is that I have to wire in the 3rd brake light...
anyone have a schematic for the brake lights?
should I pull the drivers side tail light and tap off it or run down under the truck to the trailer hook up?
The color codes would be a great help...
I already pulled the tail light and looked in there at the wiring seems like there are more wires than there should be for a tail light assy. must have some thing to do with the courtesy lights after you hit the lock/unlock button..

thanks
