That is correct. The C251 connector probably looks like one of those in line fuse holders with a diode instead of a fuse.This connection point appears to be functionally identical to what Wild Turkey suggests. The difference is on which side of the headlight diode the switched ground is applied. Wild Turkey's suggestion would appear to exactly replicate the operation of the low beam headlight switch.The 2002 lighting control system is even more convoluted than the early cars having a high beam relay, low beam relay and a dimmer relay. My commentis probably incorrect. It is hard to suss out what the function of the headlight diode is by hopping from page to page on the photos attached by Wild Turkey and I am not prepared to invest the time to print out the pages and connect the dots to try and figure out what is going on since I have no skin in this game. It is possible that the switched ground could be applied anywhere on that red/blue wire and it should switch the low beam relay on. Of course, the installer could have done something completely different. We merely point out easy ways that it could have been done and a good place to start looking.
