If so, there are adapters that will screw on an R12 service port (7/16 female flare) and adapt it to a male M10 switch port. Here is one example:

If your accumulator/drier has an unused port, the adapter may be all you need. Fittings are also available that will add an "R12 sized" service port inline that you can screw the adapter on and finally the switch.
I hope those parts are what you're looking for, but I'm not sure that everything will work the way you expect once it is wired up. The factory switch is just a high pressure switch (not a trinary switch) and doesn't behave exactly the way that you describe.
Good luck with your project! |
The accumulator is the low pressure side and not the high pressure side. I am not using the 82 factory switch on the high side which is just a single switch .You must have not understood what I was trying to do. I am using the 04 trinay switch which is used with the pcm to control the fans just like gm does. The adapter you suggest may just work to add the 04 switch to the system. But it does not show the thread size. What is needed is a m10 x 1.25. It is a male thread . The switch is a female. And yes it will work if I get the o4 switch added. This is how GM does it.
