Anyone know a source for the 3 prong plug for the pressure switch from a 98 Camaro. Triangular shape. Did this come off engine harness or from pcm harness. Has anyone wired their aftermarket ac through pcm?
did find much on search.
thanks

 

Check with Casper, CurrentPerformance, EFI Connections.. etc.. They sell OEM connectors and pigtails.

Even your local GM Dealer and Parts store would/might have a listing for them.

 

thanks bczee. Current perf had it.

 

My Hot Rod Air system is controlled by my PCM (including that pressure sensor). It works well.
