Has anyone done the 0411 swap and was able to keep the sensors stock? In my HP Tuners settings it has options for recirculation fitted, AC recirc or Fan# 2 and type fitted lists: serial, serial cycling, analog, analog cycling, passive and not fitted.

After I did my swap my ac stopped working but it could be low on Freon too as there is some evidence of a leak at the fitting by my dryer. What settings are you guys using in the PCM with the stock two pressure switches?

I have bought a later model ls Camaro 3 wire pressure sensor to use if needed.

did you get it figured out?

What year is your truck, I did the swap on my 96 and had no issues with the AC

Ok, that helps me quite a bit.. My truck is a 97, it had a V6 in it which I just pulled.. I am swapping a LS in it now, but the AC went out before all of that... It had to be low on freon, when I swapped to the 0411 I also swapped the intake manifold at the same time when I disassembled it I let the compressor sit over the side on the inner fender with the hoses still connected. It must have leaked down while doing so.

I dismantled it all last night and there was no pressure on anything and a lot of oily residue on one of the lines going into the drier. Thanks for the help guys.
