Light bar to come on with high beams

Hey everyone, I’ve seen some discussion on the topic but I can’t seem to find the answer pertaining to my harness specific to my light bar. I have an Auxbeam 22" LED light bar with an Auxbeam harness and I want my bar to come on with my high beams. My reason for doing this is because the on/off switch has a red light that stays on when the light bar is off. I don’t want to worry if my battery will die or not. Also my 7 hear old rides it and I don’t want him to forgot turn it off. I have a 2016 700. Any help would be appreciated.
