i coverted to a 92 firebird serpentine set up, my quest is, what did you guys do with the a/c wires on back of the compressor, its two wires, i think its for pressure, did you just twist them together?

total of four wires, the grn&blk that cut the compressor on, and then theres two more on back side that has a small round plug

The backside is a high pressure switch. You definately want it wired. Otherwise you will blow up your lines. Wire it in line with the low pressure switch. The low and high pressure switches are wired in series. If either is switch is activated, the compressor is shut off.

Take the hot out wire from the low pressure switch. Wire it to one side of the high pressure side. Wire the other side to the hot compressor wire. Wire the ground compressor wire to a good ground.

i plan on also doing this swap, did the wires for the stock alternator reach to the other side and did they hook up?

you will need 2 make or buy a plug with resistor, depending n whether you have a light or gauge. i bought the plug end from an alt. shop, and the resistor from electronic store, but if i do it again ill just by the adapter

ok did all the existing stock wiring reach, my alternator is on passenger side and with the serp bracket from the 89 chevy that i have its on the driver side, was yours the same??

bowtiecb · 05-28-2010, 07:03 AM
