Everyone-
Spurshot is correct, if you are running extra lights up front for additional lighting you will need to have them going to the High Beam signal. I will be eventually adding a 20 LED light in the slot above the license plate for Deer Season purposes, and at that point I will only run that through a relay and turning on when only the high beams are on.
However, if you are like me and just want the fogs on no matter what, and especially when the parking lights are on run it through the #22 slot. I confirmed it this morning on the drive to work that as soon as I fired the truck up the fogs were on, and I switched to High and Low beam several times while driving in. No issues at all. Like I said before best 0.50 cent modification I have ever done.
