Re: NOT so EZ wiring
Does your PCM have two wires for the TCC switch, or just 1? I only had one on mine - unfortunately, at this point I do not recall which connector and number the wire was, but I am positive I only had the 1 wire. Ultimately however, the 4 prong switch you have shown should also work as long as you wire it correctly . . . brake normally open side (so when you hit the brake the switch closes making connection and applying 12V to the tail lights) and TCC normally closed side (again when the brake is depressed the signal is opened disconnecting the TCC). Two wire should be all you need, unless your PCM calls for two relative the TCC, so at that point you would need the three.
