Default AC compressor clutch help

On my 85, I am looking at the schematic that shows the two black AC compressor clutch wires as 50 & 59 but they dead end at the manual transmission plug, which i do not have,,


Can some one tell me where the two wires should end up under the dash?

The plug looks like this, can you tell me whihc sockets the pins go into? A,B, C, D etc?

You didn't say if you have a C60 manual AC or the C68 Auto Climate control.
Looking at your prior posts I'm assuming you have the C60.
Here's the schematic for a 86. Not sure if your 85 is the same.

The compressor clutch has two wires. Black wire goes to ground G104
located rear of engine below Left Hand valve cover.

The other wire turns into a Light Green wire and goes to Pin C of connector C1
which plugs into the C60 manual control assembly.

Thank you! I had the ground wire correctly wired, the Pin C is what I needed!

Found the problem, the diode at the compressor connector plug blew and was arcing the two wires together to make a dead short
