Temp Guage ??? - HELP!

[grlaneriejr]

Got a problem. Took out my radiator to do some engine work and now my temp guage doesn't work. I think it could be the coolant sensors at the bottom of the radiator are not hooked up right (put the wires back on wrong)

Could this be the problem? If so, does anyone know which color wire goes where on these sensors?

Any help would be great.

Maybe you accidently unplugged sensor switch on thermostat housing, that brown one which sends temp. to your guage.

I have the M10 engine w/ 2 temp sensors on the radiator. No wires on the thermostat housing.

Does anyone know the wiring color placement for these sensors?

I don't think those senders have anything to do with the temp guage. AFAIK they are the high and low speed switches for the aux fan. I'm not all that familiar with the M10 so hopefully someone will be able to tell you where the temp sender is.
