i am installing ac in my 86 iroc. i hooked up the control, all vents, ducts,anway on the high side line there is a electrical connection what plugs into this line?
fan switch, AUXILARY FAN,OR WHAT also in the wireing harness there is a connecter with 4 females in it. what plugs in here. same wiring harness as all the stuff coming from the climate control.please

 

I believe the switch on the high side you are talking about is the high pressure safety switch. Incase line pressure gets to high, it sends signal to ECM which cuts off the compressor clutch. Prevents line pressure from getting to high and blowing the relief valve out on the back of the compressor.

There is a 4 wire connector that plugs into the blower resistors. Plugs in on the heater box usually.

 

no im talking about a sqaure connecter with four females my resister is plugged in.

 

High speed blower relay maybe? Does that plug also end right around the heater box area?

 

no the relay is hooked up.blower is hooked up, nothing matches the connecterif anyone with tpi 88 iroc withe ac has picture that might help please
