I want to install a transmission temp gauge on my 2000 silverado 1500 ECSB. I have heard that the truck is already wired for it, it just doesn't have the gauge. I don't know for sure though. If it is, would it be easier to put in something like this? http://www.tunersdepot.com/Performan...max-35580.html or go ahead and get a new cluster? I'd really like to keep the one I have now, rather than get it flashed with my current miles. Any help is appreciated.

Thanks
