I had a Ramsey in my old 87...the plug went bad. I went to tractor supply, purchased a 4 prong male female trailer connector set and converted the pigtail to something commonly found... Less than 10 bucks.
If you need the whole wire harness use a dual momentary on center off switch with whatever length insulated trailer harness. Voilą less than the 100 or so of the original harness from Ramsey.
