if i remeber right the orfice tube should in the condenser's outlet line and with the r-134a fittings its usally the same on all vehicles. the only time it would be different would be a vehicle that used R-12. they made the fittings for r-134a different so you couldn't mix the to

i knida have a bad fealing about this so i thought i would throw it out. i wired the compressor threw the high pressure port so the pump will shut off when the pressure gets to high. i noticed it cycles about 10 times a minut but it still blows cool air. the condensor has about 3 bent tubes could that cause something like this to happen?

well the wires are riged differently i ran a wire to the high pressure switch then to the compressor so the compressor turns on with a toggle switch then shuts off when the pressure is high then when it drops back down it cycles back on
