I have searched for an hour now and all of the links to c100 diagrams, most on "ATGO" aren't good anymore. I'm building an 85 Z28 with a carbed ZZ4 crate motor, the original c100 harness was hacked by the previous owner... So now i'm left wondering if i should try making my own c100 harness for this car or do they make an aftermarket one, or can i steal one off my 91 rs v6 parts car and modify it. And by the way, all these wires are driving me INSANE!! Any and all help is much appreciated.


Also a working link to c100 diagrams would be nice too.

ok, i did some more searching and finally found a c100 diagram link that worked, question still stands though, should i try to make my own or does someone sell one?
