Johndeereman, Anytime the ground current return path is weak or resistive badddddddd things start to happen such as turn or brake lights flashinG where theyre NOT supposed to and weak lights etc etc and ESPECIALLY poor electric brake performance cuz the current is seeking alternate return paths. YOU SIMPLY GOTTA RUN A SEPERATE DEDICTAED GROUND WIRE CIRCUIT and include it among the wires in the trailer connector plug n receptacle......PERIOD........ Im NOT saying a ground is impossible via the hitch n ball buttttttttt its best to also use what I post below.
I like to bolt n tack weld a stainless steel nut n bolt direct to the trailers iron frame and run a wire from it to the plugs ground terminal and then at the trucks receptacle do the same. If the truck has ready made receptacle and/or you can use a wiring harness adapter it should already have a good ground return (still dont hurt to supplement it per the above) but you still need the good trailer frame ground ya know.
Its sooooooo simple n easy n can only help so I suggest you do it.
