which wire is for the temp gauge
There isn't one...the temp gauge along w/ tach and speedo are fed serial data from the PCM.
I added a 1998 Camaro temp sender to the passenger side head...these have three pins instead of two like the '99+ units, the third pin (C, I believe) is for gauge service.
The sender and hood were ~$15 total at the local dealer, just one more wire to add to the harness.

Just like the oil pressure, make sure that the sender matches the gauge. I added a second sender (in the passenger head like Crainholio) for my stock 1970 gauge but the sender doesn't exactly match so it reads high. (250* indicated is really 195*. I was a little nervous when I first ran the car, until I confirmed the temp was wrong with a scanner.)
got the oil pressure gauge to work will try the water temp one sunday night probably. I have after market gauges but want my factory gauges to at least look like they are working thanks you guys for alll the help couldnt have done the conversion with out yall

Probably a stupid question but is there ANY way to take advantage of the readinds made by the PCM and the serial data to make gauges work? Maybe its too much work but just curious. Would it require the body module from the same vehicle along with harness and gauges or what? I will be running a carPC when I get to that point and have thought about just putting a monitor in my dash and running something like Virtual Dashboard to display info. Just a thought... but thats a little ways down the road.

It's all in the gauge cluster; the body module has nothing to do with it.

Thanks for the speedy reply... if I was to acquire a guage cluster from an LS1 car could they be made to work fairly easily with my conversion? I know the cluster isn't likely gonna fit into my dash, but the electronics could be made to work, right? Lemme know.

Yes it will. Just kill the bulbs that don't apply to your swap and the rest of it will work fine. The only gauge that won't work right would be the gas gauge.
You could hookup the check engine light and oil pressure gauge, and let the serial data line do the rest.

Next off, do you think it would be possible to find and gut the actual PIC and use it with other gauges... of course, guessing that the LS1 gauges are basically the same as the electronic gauges in my VX... Just REALLY curious. Of course, I can always go to plan B... just gut my gauges, install a monitor in my cluster and run Virtual Dashboard for my general readings. Just a thought.
TTYL!
