December 13, 2007Hi - My '02 HD has a switch on the dash that says "auxilary lights" but nothing turned on when I tried it. I looked at the manual and it said that it is used for roof lights and to look under "snow plow prep package" in the index for further info. Lo and behold, the index says nothing about a snow plow prep package! I assume this must be for a beacon light for plowing etc.? Has anyone tapped into this some how for wiring up, say, driving lights or something? How is it done?
