depends on motor, accessory drive setup and referigeration lines and fittings that are available to fit your compressor and whatever vehicle it is installed into. If it's gm you are ok if it's something else then it depends on how the switch is designed to function in the oem application. If you can get us some more info it helps.

Take a look here

for A/C fittings and hose. Also look at www.docsblocks.com
The GM A/C pressure switch screws into the fittings that have a Schraeder valve (like those found in your tire valve stems). Call the above supplier of beadlock fittings and get them to help you figure out what you need. Local guys like some NAPA shops can crimp beadlock fittings for you.

Find a line that runs from the condensor to the evaporator on a 1996 to 04 4 cylinder s10. It has a fitting exactly like that with a three wire pressure switch. Cut the line about three inches on either side of the switch fitting and have the a/c shop weld barbed fittings on either in end and put it in line between the condensor and the evaporator in the liquid line. Then they will put referigeration grade hose on either end with the correct fittings for the condensor and the evaporator and you can hook it up and you are done.

It is a very thin mateial and difficult to weld. The rethreading works for me and I have the Vintage Air with a Waeco control hooked up to the PCM as per the wiring diagram you can find in the FAQ.
