Wiring Problem 2002 Buick Century

Buick Century

The wiring harness was cut in a wreck. I have connected all but three solid black and three solid grey wires. They are identical. Which do I connect to which? Or does it matter? They say they go to the throttle sensor and neutral switch. Please help!!

PCM Wiring Harness Issue

You will need to identify which wire is connected to each terminal coming from the PCM. You can do this with a multi-meter by checking the continuity from the pin connector at the PCM. Then using a wiring diagram correlate the PCM connector pin with each wire and this will let you know where the wire is supposed to go.
