If there is no backlight, then simply ground the wires it tells you to.

It does have a backlight but i thinks its on all the time. So two grounds? It just seems odd but whatever ill try it. The sensor wire is correct though? Im just gonna run a 18gauge wire from the little adapter thingy in the radiator hose. (with the sensor in it) Just wondering, why does a gauge need a constant? Thanks Bud!!!
