I finished using the meat thermometer from harbor freight and dissected the probe end. If you pull the gauge away from the probe the little sensor at the end can be snipped and there are 2 solid metal ends that I then jammed down into the trail tech sensor molex (no soldering!). Used electrical tape to make sure the connections don’t come apart.
I basically just use a temp gauge after I build something to make sure my temps aren’t crazy, then take it off.
Seems to work and the only issue I had was buying a resister plug to prevent the gauge from jumping around so much.
I’m happy and don’t need to do the major work on a trail tech. Yay!
