Trailer wiring help

[seachangeexcavation]

I did a temp fix by digging into the junction block (side note Load trail the manufacture uses this odd connection style I refer to as a junction block to connect the 7 way plug with the rest of the trailer wires. It’s a hard plastic but almost shrink melted around the wires.) and was able to expose enough to solder and heat shrink the connection. I’ll be tearing it all apart and Adding one of these which I’ve put on all my other trailers. Much easier to work with.
