Hi stangers i have a 1988 mustang mass air 5.0. I am recently installing a/c, i have all the pipes in place ready for r134. The very last piece of the puzzle is the compressor clutch wiring. My problem is when i install the WOT relay it will engauge the clutch like its suppose to, but once i push the relay the rest of the way it disengages the clutch. The low pressure switch is jumped too.
So far i have tried a new relay( same problem), cleaned the pins, squashed the pins. It seems weird and an easy fix but im still scratching my head. Has anyone ever had this happen? Or a fix

Well i just pluged the relay in slowly while watching the clutch and it worked!!!. Went into the var turned the switch a couple times and it stopped........
