Installing the gauge was simple. Got it wired without problems also. I changed the sensor and hooked up the wire to it. started it up and it just pegged out to the hot side. Not sure what to think now. I not sure if I am missing a harness or not, the old sensor for the idiot light had two wires comeing out of it and the sensor for the Temp gauge only has one connector. If there is anyone out there that has one on their sled or has installed one, I could use a little help. Thanks.
