I’m doing the 02 express van 0411 upgrade on my 89 GTA using a new wiring harness from efi connections. I’ve run into a little problem, I think. I want to use the Holley mid mount accessory bracket system but I’m unsure if I can use the ac compressor that comes with it since it is a 1 wire compressor with no high pressure switch in the back of it with this upgrade. Can I follow the mod instructions from original air website for the factory harness but using my efi connections harness which has the same compressor connections as the factory harness? Or does the 0411 ecm control the compressor and I’m sol.
Orginalair.com offers a complete upgrade kit for our car with the sd7 compressor. According to their website and using the factory engine harness one just needs to cut off the connector that plugs into the back of the original pancake compressor and tie the two wires together. Then only use the green wire from the spade connector for the ac clutch and attach it to the single wire on the sd7 compressor (same compressor that comes with the Holley kit). As stated above can I do this with the efi connections harness and 0411 ecm? I hope this makes sense. Any help would be appreciated.
Original air upgrade kit Sbc Holley mid mount accessory bracket kit. I like this because of the water pump design. No longer have to remove everything to replace the pump. Just take out the impeller.
