AC electrical component locations

[oldschool90]

Just wonderin if someone could tell me where all the electrical components are for the AC in my 81 720. Bought it off a neighbor and it looks like he jerry rigged it and messed everything up.

 

Heres what Ive got:

 

 

wire from wiper fuse to terminal closest to engine on switch in heater controls

wire from center terminal on switch in heater controls to a ground near the battery tray (i think, too dark to double check right now)

(the first two wires might be switched on the switch but idk)

empty terminal on switch in heater controls

wire from compressor to + side of battery

 

Heres what the manual says:

 

red w/ yellow wire from low pressure switch goes to terminal for option connector for heater, also goes to thermo switch

red w/ blue wire from thermo switch goes to compressor switch, and ac warning light

blue wire from compressor switch goes to heater option connector, ac relay, intermittent wiper amplifier,fuse block, heater relay, wiper motor, and washer motor

red w/green wire goes tofan switch, ac lamp, and ac relay

red w/ black goes to option connector, F.I.C.D. solenoid, and ac relay

 

 

I know this manual covers multiple models and stuff, so can someone be so kind to tell me where everything is on my truck? Thanks!

The one I was looking at was Haynes, but I also have what looks like a service manual that I was going to look at tomorrow.
