Ref 70 chevelle, with air conditioning and Idiot lights, 350 turbo 400cid

I have 2 relays under the hood up by the firewall. One is bolted on top of the air-cond box, the other is bolted to the plastic wiring harness holder that that is attached to the firewall.

I guess for now, if someone could ID them for me, and maybe what color wires are associated with them. I'M thinking the one that is bolted to the plastic harness holder might be for the TCS, but I'm not sure. The overall integrity of the whole wiring harness under the hood and under the dash is in really excellent condition, but I got a few thing to sort out.

I did spend some time searching with mixed results. Also where does one go ref purchasing a wiring digram for 1970 chevelle.

Thanks

Anderson,
I just emailed two pages for the front of the car. They are from the 1970 Chassis Service Manual for Chevy, Chevelle, Etc ST 130-70, available from most restoration places.

Good luck
Chuck
