So I replaced the heater core successfully but when I glued it all back together the AC compressor  clutch would not kick in. It was working fine before the heater core. Everything else works.

At the same time I decided to remove the dealer-installed security system. So I’m figuring I have a wire not connected yet.  That red one coming out of the instrument harness to fuse box 15 prong connector is my prime candidate.

And help me to understand what the wires wrapped in gray vinyl go to. Some sort of round 5 wire connector above the fuse box. One of the wires goes through the bulkhead down to near the driver headlight.

Fuses all good. Mode control and fan motor working fine. I jumped the compressor clutch direct off the battery and it engaged normally.

Any ideas? Thanks folks

 

Yikes.  Get the exact wiring diagram for your year and model.

 

I have the service manual, but my electrical schematic deciphering skills are limited. I was hoping someone would recognize where that red power wire goes by sight.
