Wiring diagram for Overdrive Switch needed?

Ramcharger, Trailduster & Power Wagon Grrrr!! Tough Trucks! The Dodge Ramcharger and Plymouth Trailduster were full size SUV's that had good looks and brute strength. The Dodge Power Wagon was comparable to them in toughness, but came in pickup truck form only.

Default Wiring diagram for Overdrive Switch needed?

Hi All

Looking for a wiring diagram for an overdrive switch (Chrysler part 56003266), came out a 1990 Ramcharger. It has four wires coming out the back these are:-

Orange / white
Blue / white

Can anyone help as tried searching net but no luck.

pm me your email and I will try to scan and email you a page or 2 from my 92 FSM.

The blue white appears to go straight to a connector while the other 3 go to a overdrive control module that it says is behind the glove box rt side. I only ever remember seeing a ABS control module back there, but who knows.

It has different wiring for TBI and MPFI engines and the colors don't look all the same, but maybe it would be close enough for you to figure it out... then again I believe all of them in 92 had lock up torque converters as well.
