Hey guys, a while back I got a Cajun Injector XL Double Door Model second hand and it worked once and than the thermocouple would start sticking making the elements never energize. So I decided I would just gut the stock electrics and build my own standalone PID box to control the elements within the smoker. I drew up a quick diagram and would love for someone to check my work before I start working on this. Sorry about the state of this diagram as I'm really not very good at creating them efficiently. Thanks for the help guys.
