How do u find out if this fits your vehicle? I have an Oldsmobile Bravada (GM)

I made it work. You are gonna need to know the size of hole and thread size of your water outlet/thermostat housing and then see if the switch/sensor matches those dimensions. I have an 1983 K20 that I installed a dual fan assembly from a dodge charger into and wired up this control to my trucks thermostat housing's temperature switch. Yours is probably different and will require some homework to wire it up--hint: hotrod forums are great for research.

Does this have a hi and low modes or just on and off?

Just one setting. I used it for about two months with a dual fan setup but kept having issues so I built a relay pack.
