Update:
I rechecked ground wire . Good.
All lights work on trailer when bronco is not running .
Only running lights while Bronco is running.
Flashers, Trun , Stop do not work when Bronco is on.
It’s like once the vehicle is on the computer takes over and doesn’t like whatever is going on .
I installed these on my 22 base and the trailer lights do not work. The wiring kit is for the bronco without led lights.
The hitch went on easy . The wiring was easy. Wondering if my ground may be bad. Has anyone used this wiring kit?

I think what you don’t want to do with any new engine is hop in and drive hours across country at a constant speed . You want to drive at different speeds during break in period so piston and rings seat correctly.
