I have a 1952 Dodge M37 sitting on a 1994 F250 frame with 7.3 idi. I'm trying to hook up a Stewart Warner aftermarket speedometer to the Ford wiring harness. My question is the color of the wiring I have to use for the speedometer sender. There are 6 wires going into the back of the factory speedometer.

You'll need that PSOM anyway, or the TCM will not shift the transmission properly. I have a '95 EVTM at home, and the wire colors should be the same; I'll check later.
