I have a new set of PIAA driving lights mounted to a Westin bull bar. I am going to use a 3 way switch so that in the first position, the lights can be turned on at any time. In the second position, the lights will be shut off and in the third position, the lights will only come on with the high beams. I know this question has been asked before and i tried to find the answer. What wire do you use as the trigger wire for the relay? There must be someone who has their driving lights tied to the high beam circuit. Any help would be appreciated. Thanks.
