It's the trailer wiring that was gone. No problems on the vehicle side. The trailer wiring was just plain rotted away, nothing left but copper sulfate and insulation.
I had no choice but to rewire the trailer from scratch. That is precisely why I was looking for a good 4-pin plug that could be installed on my new wiring like you can with a 7-pin Pollack plug.
This time I used all quality marine grade 16ga wire. Wasn't cheap, but it is nice stuff to work with, much better than the "primary wire" you get at the auto parts store.
Unfortunately I still haven't found a good 4-pin plug. All the vehicles I plan to use to two this trailer have 4-pin, but not all have 7-pin, and they're not all my vehicles so I can't demand they change plug types.
In the meantime I had to tow the trailer so I ended up using a cheap 4-pin plug from Walmart, and more heat shrink butt connectors.
