I'm looking to see if anyone on here has replaced their trailer wire harness. I've been dealing with Jerry at Boatmate for a while now on some lighting issues with my trailer. I have an '07 single axle that did not have dedicated grounds and I had to run a jumper wire over the swing. The newer harness has dedicated grounds and won't need a jumper wire. I'm hoping someone on here has done this and has some tips or tricks to make this easier.

Thanks for any ideas.
