I got a free tank and pressure switch I would like to run oba on the Toyota have a question about the pressure switch it has two male terminals so do I run the 12v off my existing ac on power to one terminal then run a wire from the other terminal to the compressor
Mine is run inline to the hot wire from my switch to ac compressor. No relay. Its just a small electric clutch, doesnt really need one as far as I can tell.
