Im looking for a 1990 dodge truck 4x4 ECM pin out diagram. Any body got a FSM laying around they want to sell? Thanks Ken

In that year, the ECM was called a Single Board Engine Controller (SBEC) and the pin outs will depend on diesel or gas and gas engine size. I have a '92 manual (might be the same) and could scan the page for you.

I have a 318. In my 1994 Dakota manual there is a page that lists colors and position of all wires coming out of computer. Thats what Im after. Thanks

Kinda hard to scan the page in a printer but here's the best I can do. Again, this is from a '92 book.

1990 is probably tbi 318. my 1991 is 318 tbi. 1992 is probably magnum 318. don't think they are the same computer. might be wrong.
