As I get int the wiring uder the hood of my 70 El Camino I am finding more and more terminated wires. I could ask for assistance for about 5 Different wires or for information on accessory wiring schematics. Most of what is messing with me are Air Conditioning, Wiper moter, TCS and what I think are buzzer wires? (I don't no for sure) most of the wires are on the passenger side of the fuse block plug. I cannot find wire diagrams for the accessories. Can anyone help?

Thanks Dean But no AC stuff. I think it is best if I replace the whole under hood harness. Any one know whats is best?

I bought my '70 replacement wire harness from M&H...good stuff.
Also, I think a wiring schematic would greatly help you...available from most any Chevelle parts vendor.

Perhaps give M & H a call and ask them about getting a correct harness.

AC harness for 70 is a separate harness and not part of the under hood engine, light harness or the under dash harness.

That is what I have also realized, It looks like I need 3 different harnesses for under the hood. I wish it were not in such bad shape, the wires are very brittle. This is an unexpected expence. The price you pay for an Arizona car, but it beats rust!!!

I can't offer much help, but I also give a thumbs up on the M&H harness quality.
