1999 9300 Eagle - wiring for the air conditioning

Son picked up a 9300 and asked for help with the air conditioning. The compressor is not getting power. When I looked, the PO had bypassed the factory dash switch with an on/off switch and there's a broken connector. There is power at the fuse panel, but nothing at the connector.

So, I'm looking for a wiring diagram, as there is other wiring that has been modified (butchered). Interesting that he had another 9300i of the same vintage that also had hacked up wiring. Anyway, I'm at a complete loss - hope I don't have to manually trace every wire!

Hoping you good folks that have been down this road can point me to where I can find wiring diagrams for this beast.

Thanks for any help. Entertaining comments are also welcome.

 

Thank you! This helped get the A/C working again. Who would have thought a 1996 9400 manual was what I needed for a 1999 9300? The logic of International, of course. Again, thank you!
