'80 300TD AC wiring

[JimmyL]

First of all, I'm an idiot. With that out of the way...
I bought this car from a scumbag as it turns out, and have had numerous issues. The latest has to do with the wiring for the AC. The ACC is disconnected, and the compressor and fan motor are hardwired to 2 toggle switches below steering wheel. (It came that way) Well, The AC compressor has a connector with 2 wires, brown for ground (melted now), and blue/green. A wire was piggybacked to the blue/green wire which went to toggle that turns on compressor. The wire kept coming out, so I decided to clean up the wiring alittle tonight. Well, I connected piggyback wire to brown wire (oily, my mistake) and melted the brown ground wire all the way up the harness to the frame behind instrument cluster. This story is too long, so a simple question. The blue green wire goes from compressor to pressure switch, then to temperature switch (per Haynes). Where is said pressure switch and temperature switch? I assume I will go from compressor to pressure switch, then to toggle. Other side of toggle will go to 12vdc. Right???? I was going to attach a picture but camera batteries were dead. Will post pic tomorrow if it will help.
Thank you,
