Trip, Trigger, Signal Wire for reverse lights using relay.

[RAM REAPER MAN]

I'm wanting to add some reverse aux lights to the rear bumper. I've done this before with other vehicles but I'm concerned with possible trailer mode coming on or glitches/triggers?
What's the best source to go from and is there any other items I may need to work properly.

I spliced into the 7-way wiring, no issues.
If you do not want to go that route, then fuse tapping the 20 amp F12 to control a relay would be an other way to do it.
