really need wiring diagram for 1990 Chevy Beretta GT 3.1 liter V6
Really need wiring diagram for 1990 Chevy Beretta GT V6 3.1 liter. Need to know where the rpm signal comes from. And if I can check injection pulse at Connected or PCM??

PM replied to for the RPM (Tach) signal info... Yes, you can check injector-pulse at the injector-harness four-pin connector, or even the PCM, the noid-lights just don't plug in to either harness like they do the injector connector.

This diagram matches, I'm familiar with this graph so if you were to say C12 wire I'd be familiar, quick learner
