2015 Sebring 200, back-up lights

[pjtoledo]

back-up lights do not illuminate in reverse. they do illuminate when engine is turned off with keyfob, all rear lights illuminate then..
wiring harness to trunk lid was repaired, it broke several wires at a severe flex point.
anybody know where I can access wiring diagrams?
so far Google & Youtube aren't much help.

there were 2 white/green wires in the harness, I had them crossed. all is OK now.
