Temp guage pegged at Zero
I was changing out a header gasket the other night and I removed the connector to the temp sending unit in the head that send to the dash. Then forgot to put it back on. I drove the car half way down the block and noticed the gauge wasn't registering. I pulled over expecting to see the wire melting against a header tube. It was close but the wire and connector are still fine I've followed the wire further along there doesn't appear to be any cuts/ damage.
I assume that grounding the wire should peg the gauge to the max while unplugging it has the opposite effect?
I've removed this wire a hundred times without issue in the past.
Any ideas?

Re: Temp guage pegged at Zero
I took apart a spare cluster and replaced the temp gauge. Problem solved.
Turns out that with the wire unplugged the gauge pegs to the max not to zero. I figure this might be useful info to someone in the future. Had I known this I would have more likely to target the gauge than the wiring as the problem.
