The critical thing is to identify the correct pin locations, as indicated on the front of the socket (that the ASR module plugs into). To ensure I didn't screw it up too bad, what I did was to cut the 1st wire (once my confidence was high that I had identified the right one), then I connected a continuity tester between the cut wire and the correlating pin slot - basically the front & back of the socket. When I established there was continuity between the front of the socket and the cut wire, I knew I had it right
