Just finished wiring my aux reverse lights. I have them wired so they come on in reverse but only when headlights are on or I can use the aux switch to turn them on. I used a 5 pin relay and tied into the trailer wiring harness.
87 is wired to the taillight
87a aux 2 switch
86 reverse lights
85 to ground
30 out to new lights.
Lights are the 7" slim led off amazon.
