Hey Bob, thanks for reaching out!

In order to get the Aries 20" Single-Row LED Light Bar # AA1501262 to work in tandem with your high beams, you're going to need to tie in the power wire to your high beam light circuit.

I'm not sure what wire that is, but if you use a circuit tester like part # PTW2993 you'll be able to trace what power wire that is and you can tap into it that way.

Are you planning on installing this on your own, or having a shop do it for you?
