Does anyone know where I can find the ignition harness wiring diagram for a 1990 Chevrolet CavalierZ25? I've been looking all over and all I keep finding are the manuals to purchase online. Kind of need the diagram really bad.

Any help is appreciated. Thanks.

well what exactly are u looking to find in the harness?  if this helps...the constant 12v is red, there is two of them.  the ignition is pink.  the starter is yellow.  and i think the accessory is orange but im not sure.  now when u look in there, you will find other yellow wires that arent the starter wire.  all the wires i mentioned above are thicker than the rest....so they should be pretty easy to find.

Thanks. They're checking for power to the crank? I have no clue, I'm looking this up for my husband.  They've already replaced a sensor, and that wasn't the problem. The car made a "whump" and then sounded like it was running on two cylinders before it died. Personally, I'd check the timing belt, but what the hell do I know?

Why is so hard to find a wiring diagram for a car, yet you can get any MP3 and all the porn you can handle? I just don't get it! LOL
