<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by pape:<BR><B>Is there a mod or part that allows the foglights on a 1998 XC to be switched on independantly of the headlights?</B><HR></BLOCKQUOTE><P>Usually the fog light relay is wired such that the ground is a "switched groud" using the high beam positive as the ground which cuts out the lights when the high beam is on (effectively cutting out the ground, hence "switched ground"). The power source comes from the low beam source so you cannot turn them on w/o the low beams. <P>Using a wiring diagram, I was able to change the ground on my `93 Talon to a peranent one. I simply took that wire and, well, grounded it. I left the power supply in tact so fogs could only come on with headlights to avoid leaving them on accidentally, but you could change that source from switched to constant too, provided you get the aforementioned wiring diagram.<P>But I will warn you, I had a switch go bad on my years ago (not the talon) and the fogs came on, all by themselves, with the car parked at a train station for 10 hours. Very funny to get off the train and see your car "looking at you" with lights on. Can you say Christine?<P>A crowd gathered around becasue some old man walking his dog came over to say they came on first thing in the morning... suffice it to say, DIE HARD was a die hard that day. STARTED RIGHT UP! Replaced the switch though.<P>Just my .02<P>
