Yesterday I installed the bypass toggle switch, I had to go with an ON OFF ON switch Menards didn't have the rocket launcher but this one works great. It was actually a lot easier than I thought it would be, even drilling the half inch hole wasn't bad, started with a smaller bit and worked my up using a little oil and it went pretty quick. If you've been thinking about doing this jump right in the instructions on page 4 and 5 are really great, the whole process is maybe a couple hrs. and the cost is under 10 bucks thats with buying all the connections if you have those on hand it would be under $4. If you have done the bypass and installed a permanent probe for the Auber it's no more difficult than that, can't wait to try it out this weekend on a couple of chickens now crispy skin is just a click away how cool is that! Just made the best smoker on the planet even better !!
