Help - Wiring diagram needed

[Wageslave]

Does anybody have a diagram for the ECM in a 1983 El Camino with a 3.8 and dummy lights? I am switching over to a TBI computer now, and there is a small bundle of wires that go from the dash to the computer harness. These should be where I can power the computer and connect to the ALDL connector in the dash, but I really don't want to rip the dash apart to sort them out.


Thanks in advance.

Unfortunately, no ECU schematics on that page. My Haynes manual doesn't even cover the computer very well. It only says typical V6 or V8.

Maybe someone here can post a snippet from the GM service manual with the ECM wiring

what about at one of the parts stores that have a computer for customers to look up repairs

For an 86 Regal yours may be similar

These diagrams are about perfect. When I started testing out the wires to figure out what went where, I found the wire harness that I had cut from the computer harness had been unplugged upstream and had some power wires reappropriated to run the digital dash. This may be the time that I redo all the dash wiring correctly - god help me.

Thanks

Winner, winner, chicken dinner! The connector at the bottom middle of the diagram is the one that I was concerned with.

Thank you
