Howdy. I pulled my engine out for a rebuild over a year ago and have it back in now. Unfortunately I lost my notes about what wires go where and would appreciate any help you might offer.

The numbered tags you see on some of them were from a head gasket replacement a few years ago. They worked great! Too bad I cleaned them all off the engine side.

1991 base Metro with standard transmission.

Thanks in advance.

Matt

I don't see your starter wires so I hope you know them.
This was an automatic so I think plug two might be your shift light.
It pretty hard to mix most of these wires. Good Luck!!

Okay, got it all together. New info:

#2 goes to a plug near the EGR valve. Found the shift indicator further down the harness.

My #7 was black with a yellow stripe and goes to the starter solenoid.
Your (UncleBranton) #7 above is yellow with a black stripe and goes to a sensor on the intake manifold.

I distinctly remember this not being hooked up before on mine. What is it? Where does that yellow/black wire come from.

Off to hook up vacuum lines! Thanks again for the help!

yellow with a black stripe and goes to a sensor on the intake manifold. that is the a/c cut off switch if the coolant gets too hot...
a/c will not work properly if this wire is not hooked up...
