There are about a billion different threads in the 60 section that all talk about how to wire up the chevy compressor when you want to use it with a/c. Since there are some dudes in here that I know have dealt with this I figured I'd just post up in here. After reading these threads, I basically understand 2 things. I need to connect the original wire from the toyota wiring harness that is black with a white plug to the new chevy compressor. Also, there is another wire I apparently need to connect into the tach. What wire is that? Does anybody on here know?
