I've been searching for days on how I would wire up my BD S2 backup lights to both my reverse lights and also an upfitter. The outcome im looking for is to have the extra lights come on when I shift into reverse as well as by themselves while in park with the press of one of the stock upfitter switches. I like the extra lights when in reverse but also would like the extra light when loading up the fifth wheel, in the desert when we're tinkering or crawling around rocks. Any ideas? Thanks for your help.

A single relay should do the trick. One leg from the aux switch positive. Another leg from a tap on the reverse light; you can find that in the 7 pin connector. Connect both to 86 on the relay.

30 is a constant hot from the battery, 87 would go to the light and 85 is a ground.
