I am in the final stages of getting the AC in my car to work using the LS1 PCM. One piece I need to sort out is the size and pitch of the stock 98 Camaro LS1 AC pressor Sensor. It has female threads and it does fit (roughly) on an old-style schrader high pressure port, but it needs an o-ring and the threads are not quite right. I also need to know what type of port the Chevy part is called and what other cars or trucks might have one.

It is not a standard on-off switch or a "trinary" switch that also sends a signal to a fan - it is a pressure sensor that the PCM uses to know if the pressure is too low or too high. The AC Delco part number for the sensor is: 15-5742 and the GM part number is 22664328


I have called all of the Hot Rod AC places and no one seems to know this.

Thanks in advance for any help.

Where does this fit into the F-body AC system- possibly the accumulator? I haven't been able to find a good pic of one, and am trying to determine if I want to go the F-body/PCM route for AC control or stick with the Toyota setup.

It is on the high pressure line.

It appears that the size and type of vlave is a "SR10-Schrader valve"
