I've got an older Tekonsha hydraulic brake controller (unknown model number) in my 86 Ford F250 that I sometimes use to haul my tractors. While removing a couple of the previous owner's switches/modifications from the cab, I accidentally unhooked/cut a couple of the brake controller's wires. I've searched for a wiring diagram online, but can't find one for a hydraulic model.
I know that the blue wire goes to the rear of the truck for the trailer plug, but not sure where the black, red, or green wire are supposed to go. I'm guessing that the red wire goes to cold side of the brake switch, and the black wire goes to the battery.....BUT what about the GREEN wire?
BTW: I did read online that the hydraulic model is grounded through the steel brake line. Dunno if that's right or not.
Any/all help would be greatly appreciated!
