Aux lights off the high beam

[lost_in_the_woo]

I have a question for you guys.
I want to run a 20" LED light bar on my 4Runner.
I would like it to come on when my high beams are on.

How do I wire this in with a relay when the circuit is ground switched.
Thank you,

The best way i know is just a connect the switch power out to the high beam power wire where they come from the relay. This way when either the switch is pressed or the high beams are turned on the relay circuit is complete and powers the lights.

Or if you don't want the switch just leave the switch out and connect the high + to the relay terminal that would normally go to a switch.

edit:
If you want a switch and the highs, but for the switch to only work with highs on, then connect the positive in on the switch to the + from the high beam.
