1986 ac diagram using r4 compressor

[Bladeboy1998]

I was thumbing through my 86 service manual looking for either a wiring diagram or a service diagram for the entire ac system on my 86 k10 I'm putting back together. There doesn't seem to be anything in here regarding the rest of the system, just the compressor. The truck was gutted when I got it, just a cab and frame. Some of the ac stuff is still there like the receiver dryer and heater box and whatnot, I've got a couple compressor brackets I sourced elsewhere.

Does anybody have any pictures of a factory air truck wiring and hose routing and vacuum lines if there are any that apply. Thanks for the help!
