A/C wiring and relay question 700 1991

Just bought a 91 740 and I'm now working out the little kinks.

In trying to get the AC to work I noticed I was not getting 12V at the compressor. The previous owner must have notice the same thing because he has almost broken all the wires at the low pressure switch and every other connector on the system by probing them.

I straight wired the AC and it works great which points to an electrical issue somewhere.

I have hunted all the parts houses and book stores and can't seem to find a service manual for this model 740. I need to look at a wiring diagram for the AC system. Can any of you help?? Where can I find a service manual for the '91 740? do any of you guys have any advice or experience you'd car to share with me?

Thanks,
Tony T

      I went to the techinfo site but the only way I could get a wiring diagram was to purchase a paper copy for $33. I don't mind doing that if that's the only way I can get any information but I had hoped someone here could help me out.

      Thanks,
