when u go to take the one thats installed out, cut the wires down by the connector. You do that because your gonna use the old signal switch to pull your "fishing" line up. Then your gonna wrap that around the new switch to get it back down (u want the connector & fishing wire as thin as possible). I would use a lil cushion because I felt like I was gonna break the new connector as I pulled through. If it doesnt want to go or feels like its stuck, pull back out and twist the connector 180* and retry. It will eventually go down smooth.
