Please be very specific, there are at least 7 million wires behind the CP, which I guess you mean the AC control unit inside the car, is that what CP means. I took the control unit out and there are thousands of wires none of which are just lying there unattached.

Please tell me specificially how to find the ground wire, keeping in mind I do not do this for a living I do not know as much as you and I am an amature with tools and accronyms.

The test was negative. The car when I put the positive test end on the Fuse then ground it I came up with a 7, on the black wire at the three connection nothing.
