I'm new to this forum so bare with me! What I'm trying to figure out is how to use an LED light bar with two existing switches in my truck. I have a 2017 f150 and want to mount an LED light bar to my back rack. I want the lightbar to turn on when I put the truck in reverse as well as when I turn on the cargo lights in the bed of my truck. I know where I can grab power from from both "switches" but what I'm trying to figure out is the best way to wire it. Do I use two relays one from the revere's lights and one from the cargo lights so they don't backfeed into eachother/will relays prevent this backfeeding or am I thinking too far into this? Thank you in advance!

Relays will isolate it.

Wiring this should be fairly simple. I have attached a photos/diagram for you.
