I have a LED light bar that came with a harness/relay that is wired up like the diagram below (pardon my amazing drawing skills):
I bought
this switch from Air On Board to replace the one that came with the light bar, and I'd like to wire it up so that the light bar switches on and off with the brights when the switch is activated.
Now this would be very straightforward except that Toyota uses negative switching for the headlights so I can't simply tap into the high beam's positive lead. Air On Board included the diagram below with the switch, and I am confused about the part in the box about the second relay.
Where on that diagram should I connect the high beams to the second relay (and which wire should I tap, negative or ground)?
Does anyone have other ideas on how to get the bar to come on with the high beams that don't require a second relay? Any help is appreciated, I'm a noob when it comes to wiring so the simpler, the better.
