Incredibly simple using Bronco upfitter switches!
You literally cut off half of the wiring harness, and you don’t use the relay. Simply tie the 2 red positives together to the preferred aux switch wire by firewall; and attached ground to the point right next to it. So fast and easy! No fighting getting things through firewall is amazing.
Had some wire cover laying around and covered the wires behind the lights with it and it turned out great!
Part of harness and parts I didn’t use above ^
