I think I got it figured out!
I found info that says a vehicle without the TP2 auxillary battery needs a
40 A fuse in the ( stud#1 ) location in the under hood fuse box.
( note: this fuse is not needed if you have 2 batteries )

I will check on trailer today and let you know.
Thank you for your time and your help in troubleshooting my problem.
