Good wiring diagrams
 
Does any body know of or have a source for good wiring diagrams ?

i just swapped in a new crate engine, and along the way i have been deleting all factory wiring...

inside the dash on passenger side comes all the ecu wiring, along with 2 main power circuits.
1. being 12v power to the dash (cluster, head lights ect.)
2. power to the a/c SYSTEM

WHAT I AM LOOKING FOR...
is a schematics that shows that A/C circuit...i have a lead coming from driver side fuse bulk head over to the pass side that has the A/C feed and an A/C dryer hook up....just wanting to see about powering my new A/C comp.


i am also going to post this in the general discussion thread

Helm Books is who makes the factory manuals. I ordered one when I got my '92... Not one but three books, mostly schematics. Made my head spin looking at them.

I book marked a page someplace that had all the wiring from a 93 someplace. Once I find it I'll post it. Everything is in PDF. Also Autozone has free PDF files with wiring diagrams

Those are the Mitchell wiring diagrams.

My T400 manuals thread has the 93 GM wiring diagrams along with the Unit Repair and Emissions manuals. Look in My signature.

I don't have a 1993 service manual in my library but the 92 & 94 should get you what you need.

1987 - 1993 wiring diagrams were 11x17 pages. I usually print them on ARCH B (12x18) if I need a hard copy.

The parts and illustration books are extremely useful as well but the paper books stopped in 1993. As I've said before I have fiche for 94-01 T400 trucks but it'll cost an arm, leg, and several internal organs to get it digitized.

You can find most T400 manuals on evilbay for a reasonable price compared to the T800 manuals.
