temp gauge not up

yep

Maximus. . .why don't you start by trying to find where the disconnected wire is supposed to connect instead?

does your heater blow hot air? have you checked to see if your thermostat even works...? i thought mine was stuck open, never got hot air unless i let the truck sit and idle for several minutes but once i started moving down the road the truck stopped blowin hot air inside the cab, and started blowing cold. the temp gauge would go up if i was driving around in downtown seattle, but go right back down once i hit freeway speeds...
