A/C Wiring

Anyone have a wiring diagram that shows how the A/C should be wired? I have an 89 crew. I don't know what year the wiring is out of, but it is a TBI motor... I have a green and black wire coming off the A/C compressor and there is a green wire sticking out of the harness behind the intake on the firewall. Do they go together and black is ground??

Thanks!

Levi

My chilton book is at work, and I'll be back to work on Monday. Until then, I am no help to you.

Re: A/C Wiring

Ok, just spent about 30 minutes going through my chilton book. I guess they do not want you to know a wiring schematic for the A/C stuff, not a thing in there I can find in the wiring diagrams. Everything about the A/C more or less says "It is recommended that the A/C system be serviced by an EPA Section 609 certified...." blah blah blah.

I tried.
