Please bear with me this is long. I have a 1980 Boler
13ft that had a 7 pin when I went too look at it. When I went to pick it up my truck had a 4 pin. so a 4 pin pigtail was added to the wiring so I could get it home.
We have had it out a few times and all the lights
I have since bought a different truck and it is equipped with a 7 pin connector. Should I wire the trailer back to 7 pin or leave as is.
We are going out for a few weeks the middle of August and I'm trying to get everything ready.
