Ever wanted your foglight to stay on when you go to brights
in your TJ? Well, I did too. We found the relay by putting our heads
under the dash and listening for the click while flicking between bright
and dim with the headlights on. The relay can be found above and to
the right of the fusebox behind the glovebox, at least on the '98. I
think newer than 2000 will be found under the hood.
