Hot Rod Air evap wiring

[BigBlockOlds]

The blue wire with the female bullet connector goes to the compressor clutch. You should have a safety switch in series along it on the high pressure side. HRA may not have included it with your kit. You need one.

They didn't include one by I did buy a Trinary switch that mounts to my drier. I still need to wire it to my electric fans and the Accel EFI.

There should be two wires on there somewhere that connect to the thermostat, mounted on the evaporator housing.

I believe those two wires are the blue wires in the photo above. One end is connected to one of the relays and other end has a female spade connector on it. Then the other blue wire was just taped to that one. It has a female spade on one end and just bare wire that the other. So I was figuring that the wire coming from the relay goes to the thermostat and then the other wire connects to the thermostat and runs out to the compressor/safety switch.

The fused red wire goes to the battery positive and there is probably a wire that runs to switched ignition. There will be a ground wire, probably with a ring terminal.

I only have one power wire from what it appears which is the one with a 30A inline fuse. Should this get connected to a switched +12v source instead of battery +? The reason I ask is that if it was hooked to battery + and I forget to turn the HVAC off completely, then the blower motor would continually run on low, draining the battery.
And your right, I have two grounds with ring terminals. One is for the blower motor and the other is part of the relay wiring harness.



Thanks for the help!
