Yeah so I'm installing white faced gauges and I need to tap into the switch that controls the head lamps. There's only one black wire so I"m assuming that that's the negative but there are several red. Anyone know? My car is in pieces right now so a quick response would be much appreciated! Also where's the best place to run the wiring? I don't see any holes from the gauge area to the light switch. Go underneath? Can I remove that bottom panel? Thanks so much for the help!
