Hi, Can anyone identify this harness? The owner believes it to be VS or VT but

Any help would be appreciated

Thanks

I thought the pressure switch prevented the clutch from engaging when the gas pressure and therefore oil was low?

How does it do that if it controls the fan?

Does the pcm look for the fan being grounded before engaging the compressor clutch?

HI, Trying to get my hands on a genuine GMH dealer workshop manual for a VS.

Not a Gregory or Haynes but a genuine GMH workshop manual used at their dealerships.

If anyone has one or knows where I could find one please let me know.

Thanks yoda69 :thumbup: I can't believe i forgot about these diagrams :? I was looking at these not two weeks ago... What would be the best way to bridge the low pressure switch??
