Hey all!
just looking at different ways of wiring my electric fan setup that came with my afco radiator. I like the idea of and adjustable probe that mounts externally on the radiator. I see summit has a few to choose from. Otherwise to use a temp sending unit, i am looking at drilling a hole in either my intake or radiator, and im not too keen on doing either. So, just looking for feedback on the external adjustable style if anyone has or is using one.



I use a similar unit as your picture that is manufactured by hayden. The first two I pulled off of the shelf were internally wired wrong but they have since corrected that. Check yours for correct operation prior to installation.
