If you want it "on" all the time when the ign is on/eng running then I would just solder it into the ign1 "run" blue wire circuit that feeds the reg/alt field/ballast at a good convenient point for aesthetics. EDIT If it is only supposed to be operational when the AC is on then I would T into the feed wire for the AC compressor
