2016 F150 Tow package bad ground???
So here is my issue.
Lights on the trailer are very dim, brake, turn and running light don’t illuminate. Side marker is on, but very dim.
Trailer is new. Grounds are all solid. Problem persists whether i use the 4 pin or the 4 pin to 7 blade adapter.
Now, if I half insert the plug to make the light connections and then use a jumper from the ground pin on the truck to the ground of the trailer everything comes to life.
I am assuming the truck ground is bad. But how? 2016, 18,000 miles. No corrosion on terminals.
where is the ground located on the truck side so I can check it is secure??
Thanks all!!

If the ground works running a separate wire from the truck connector ground to the trailer ground it sounds like the problem is in the trailer connector to me. If it was the truck side I would have expected the jumper to have a problem as well. It could be that the female ground on the trailer side is oversized or corroded. I would see if you can make it tighter by pinching it in some way.
