Quoted from sataneatscheese:
I can't find it, but I saw something on one of the threads where someone had used a military phone connection main line plug to patch cut cords like this. This provided a quick disconnect while being waterproof, dust proof, and relatively easy to work.
That was a pic I posted of my Williams Argosy. It was a screw down terminal style connector from the 70’s. I still own it and it still works. Was hours and hours of finding which red wire went where... there were multiple wires that were the same color!
