ECM Pin out diagram

[GTP091]

Does anyone know where to get a get a pinout diagram of the ECM Harness for a LQ1 91 GP OBD1?? I'm specifically looking to see where each one of the two white wires on the 5 wire ICM harness go to on the ECM harness. My manual indicates one wire is for tach and the other is for est control signal. since im relocating the ICM permanently i would like to know the exact configuration for these wires and the ecm diagram would be nice reference.

Hi Robert,

Can you get the fuel injector wiring harness diagrams for a 1999 Grand AM and a 2002 Grand AM?
The 1999 is Multec1 and the 2002 is Multec2, so I'm trying to adapt the 2002 harness to the 1999 GA as part of a 3500 engine swap that will use Multec2 fuel injectors. I need to understand any wiring differences between the two harnesses so hopefully I can just swap the 1999 main harness connector over to the 2002 harness.

Thanks a bunch if you can help!

ok, i see what you're trying to do...

unfortunately, GM changed the connector between 99 and 02, so that's not going to work. they seem to have added in the cam sensor.

here are the two connectors:
