96 f250 7.3 finally got the electric brakes wired up. For those curios about which wires do what here goes.

There is two female connectors one with three wires on with four.

The three wire one
Orange battery charge power, key on
Blue electric brakes
Black green stripe auxiliary

Four wire
Yellow left turn
Green right turn
White ground
Brown tail light license plate

I cut the connectors off because one of the pins was almost corroded off.

Hope it helps others.

I wonder if that auxiliary could be wired as a backup light?

 

Rep sent.
Yep I have wired as a backup light.

 

Thank you Jose'. Did you tap into your reverse light wire?

 

I really dont know, it is there since I bought the truck, but I think that you could tap there, IDK, if you need or not a relay, maybe Jim (Hussler) could chime here about that.
