IndyJimW Posted January 25, 2021 Report Share Posted January 25, 2021 The 1987 Avanti wiring diagrams pages 1-22, vacuum diagram and ECM pin-outs diagram use the original 1987 Chevrolet Monte Carlo diagrams. Some of the diagrams have been altered, usually grounds, from the original. The rest of the pages are Avanti Motors. If you have problems reading the wiring diagrams I can provide the Chevrolet page which is clearer. Good luck, Jim Wood Link to comment Share on other sites More sharing options...

Most of the wiring diagrams would be the same as in the 63-64 Avanti Service Manual or my 87 Avanti depending on options.

Good luck, Jim Wood Hi Jim, I am tracing the cruise control, auxiliary lights, power antenna, stereo trunk popper, dash gauges, choke, a/c, transmission and ECM on my 1981 Avanti II. 11 hours ago, silverstude said: Have you tried this reference? https://studebaker-info.org/Avanti/Tech/Electrical/AEC/aec.html I carried this page for years before realizing who authored them. The 81 can't be too different I appreciate the reference! This should be helpful for most of what I’ve got going on. I’m just verifying and cleaning up the wiring throughout the car to confirm full and proper function of the car and all of the options. Thanks again everyone for the help!
