I have a 2002 lincoln ls v8 with i believe is an electric fan conversion but i dont know what this is

That appears to be the controller for the automatic temperature probe. It will turn the fan on at a preset temperature which is controlled by the knob you see. I installed one with my electric fan conversion to eliminate the need to have the fan always running.

Yea thx i was messing with it and heard the fans come on it was overheating on me because the fans weren't coming on. So i have to find a sweet spot basically? So the fans come on at the right time?

Yeah, that's about it. The controller I have you run the engine until the temperature comes up then you turn the knob counter clockwise until the fans turn on. Should be it.
