Like yer truck, was wiring the fog lights a problem (going thru the firewall)?

Actually, the hardest part of putting the fog lights in was drilling the holes through the top of the bumper. Wiring was easy- what I did was go through the hole in the firewall for the emergency brake- it has a rubber ring that secures the emergency brake line through the opening in the firewall. So I just basically poked two holes in that rubber ring for the positive/negative wires, and fed them through to the switch which I mounted underneath the main console.
