Dash gauge won't move past 100 degrees

So guys my dash gauge won't move up too operating temp. I've tried ground out the gauge and it does peg out past 260, but I changed the temp switch on the side of the block and I'm still having the same issue. Anybody else run into this same issue?

I'm fairly certain the tbi v8s have two temp sensors. the dash reads off the one on the intake and the computer uses the one of the side of the cylinder head.

I thought the one on the intake went too the computer?

Side is the gauge sensor (on a 93 anyway). I have a gauge that didn't seem to read right and replaced the sensor. Still didn't read right but when I check the temp with a infrared gauge at the sensor in the head it was actually rather close. So you might want to verify the temp at the sensor

Try replacing the pigtail and a bit of the wire to the sensor in the head. The single wire can get brittle and break especially around the connector, causing no reading.

The sensor in the intake goes to the computer, the sensor in the head goes to the gauge.
