Thank you for that, it seems to be more-complete that the Chilton manual's sparse electrical data.
I am "analoging" my '83 with a 2-barrel Weber and GM-style, 1-wire distributor with the Clifford aluminum intake and Eagle header so the engine will literally need half a dozen wires or so to allow it to run. This approach seems to run counter to several other members that are currently working to get the factory ignition and emissions systems back to working order, but VA does not seem as concerned as other states as to the functionality of those systems in a vehicle this old, coupled with the fact that a lot of the people performing those inspections wouldn't even know what came on the vehicle as standard emissions equipment from the factory anyway.
The source of my initial question is that I plan to reduce the underhood wiring to clean up the firewall of my car and not have a bunch of unused plugs hanging all over the place.
I do have an '84 parts car with a complete engine bay harness that should be very similar to the '83 harness, so I am not too concerned about gutting this one as I'll have a "spare" harness to refer back to or reinstall as necessary.
Thanks again!
