Good luck

I have the same thing on my trailer. Steel frame, aluminum deck. It had real bad rust and always had electrical issues before I rebuilt it.

I avoid electrical problems by using all sealed LED lights and every LED has its own ground wire for everything. Connections are all made with heat shrinking and self sealing butt connectors.

I like to be able to grab the trailer and go and not have to screw around with non functional lights or getting pulled over.
