New 2019 Raptor owner and first time poster here, although I have been lurking for a month or so. I just installed the tailgate switch, and I must compliment you on an exceptional job of constructing the package and of writing clear, concise directions. It is a lot harder to do the later than it sounds, and is as important as the quality of the product.
Needless to say, it works perfectly, took only 20 minutes, and made my Sunday a little better.
One issue, though. Your instructions specify 1-6 beers as being optional, but as I only had my brother's stash of Coors Light in my garage, and, well, that's not beer. Instead I had to resort to dry ciders. They worked equally as well, and with a much higher alcohol content. I would suggest updating your instructions to "1-6 beers, or other suitable adult beverage."
Great job!
