Grounds...
Found the culprit in the mirror
Robbed the remote mount FSD to trouble shoot my 3500HD
I mounted it behind the left battery using the ground bolt for a wire.I had left the bolt loose to put the remote back in.
Not all is lost the wiper posts needed to be replaced,and now the brake controller will get wired in.
