sorry about the repost so soon but i realy need an asnwer, just wanted to know what cable you used as your ignition cable for your thermal switch? and wer abouts you tapped into it thanks heaps.

G'Day, when I was running a thermal switch, I used the vacuum purge plug (there is a grey plug with a grey wire above the AC compressor). Put a multimeter on it it and check it, 12V when key on, 0 when key off.

Hope that helps.

champion thanks mate.
