I have a 1992 12 valve Automatic swapped into a 70 Crew cab. Control module deleted. I need to wire up the overdrive. Does anyone know how, wire colors from trans? all the info I can retrieve the better

A light green and a dark blue. The dark blue gets power, the light green goes to ground through the PCM.

So just feed the green wire with acc. Power and ground the blue with a switch?

Other way around.

Green is ground, the PCM's always put things to ground. Another way to control the OD is to use a adjustable hobbs switch in the trans pressure port.

Yet another method that I've read about is using a potentiometer. Just search "tps delete potentiometer" for links and videos to explain how to set it up.

So it ended up being a blue power wire and an orange with green stripe wire as ground. Both wires come right out of the drivers side of the Transmission. I ran an keyed acc.+ wire to the blue wire and the orange wire to a switch on the dash to ground. Works good. Thanks
