And now on a serious note, this how you have 3 speeds on your heater fan.I searched and can't find out what this is or if I need it? I'm pulling everything out for paint before I drop the ls in.

It's a Kelsey Hayes selective resistor for trailer brakes. Since you only have one terminal connected, it's currently doing nothing.
Wow, learned about a new brake controller.Are you sure that's the heater resistor? All the ones I've seen have been in the side of the heater box. Could it be an aftermarket one? What it looks like to me is one of those resistors for an old school trailer brake controller.![]()
...might be a trailer brake control,but I bet you could toast bread with it too...
