jlbritt1 Thanks for the tip!
And just to let everyone know, I figured out an easy way to have me driving lights stay on when I switch to high beam. First off, although I was referring to them as "driving lights" they are actually the FOG lights according to the wiring diagram. There is a relay called"high beam relay"that feeds power to the fog lights through a normally-closed contact. When the Dimmer switch is in the "high beam" position, that relay gets energized, opening the contacts to the fog lights. That is the only function for that relay. So, I simply cut the wire that connects to the coil of the relay, and then it can never open the NC contacts to the fog lights. Problem solved!!!
