This one works perfectly. It replaces the melted connector that plugs to your pw switch. Just splice it into your wires. The wire colors don't match the originals, but I'll put up the color to color match below. I'm using it on mine:

The left side colors are the new switch colors, and the right side are the original harness colors.
