I have a 1988 Fiero GT with the L32 swap. I made an A/C hose up and started filling the system but the A/C clutch never kicked on. I got underneath and here we go again, there is no wires and no connecter anywhere nearby.
Where do I have to run the wires from to get this working?
I found a chart that has 4 different wires for A/C but the unit only has a two prong connection.

An 88GT would have originally had a clutch cycling switch on the accumulator in the front compartment, that had to be set at 21psi for an R-134A conversion. The original HR-6 compressor had a clutch that had 2 wires going to it to turn the compressor on and off.
What compressor is on the car now? Pics? Which ECU? Did you do the engine swap or someone else?

The compressor is what came with the L32.
It has a Intense Racing PCM
Previous owner did the swap. It's got a combination of the L32, A Northstar TB, and a 2003 Lesabre wiring harness.

Does the swap harness feature a three prong connector for the A/C pressure sensor so that the PCM can control the A/C system?
The plug would plug into a port on the A/C high pressure line from the compressor to the chassis.

What a mess. I'm trying to follow the wiring harness and go by where things would be on a stock Fiero. Where the relays for the fuel pump and AC should be there is now what looks like a small junction box. There are no leftover unconnected plugs or wires, and up front the only connecter is right to the AC accumulator.
Not sure what the previous owner was thinking or why he chose to use a 2003 Lasabre harness but I'm coming to a dead end on AC, Oil pressure, and Cruise control.[This message has been edited by TurboGN (edited 04-25-2022).]
