Well I'm at a loss now. Gauge pegs cold when full open and hot when wire is grounded. So the gauge is good, wire is good which I fixed anyway. Start the truck up and temp still sits stuck at 100. Not pegged cold, right at 100. I think I got a bad sender
Had a POS old thermostat in it that Im assuming was very stuck open. Replaced it with a Quality 195* and suddenly I have actual good heat and a temp gauge thats trying to read with a twitch in it. Moved some spark plug wire from laying on top of the sensor wire and wahlah temp gauge all good. Runs at 195* all the time.
