Ok I posted this in another thread and no reply, probably should have started here,
I’m not going to be using my heater in/outlets on the water pump housing, at least for now. Can either or both be used as places to put fan switch or temp sensors?
You could but what I'd do is loop them, then get a T fitting for where the temp sensor is from the factory, which will allow you to run two temp sensors. The later is what I did on my 408
