LT1 Swap, coolent gauge issues.

I took my car for the 1st test drive. Works fine. have vibration from y pipe touching my subframe connectors.. no biggie.
My coolent temp gauge isn't working though. I have all the other gauges working, I wired the temp sensor to a green wire going into the c100. I don't know which pin. it isn't easy to tell. Is there a test I can do? or does anyone know what it should be connected to?

thanks.

i had issues with my alt as well, you using 1 wire or 2 wire plug on it? and without the alt even bolted up, I was reading the proper voltage, albeit 12V rather then 14. I had a 1 wire hookup, and according to info, you put 12v on it and it should charge. Well it didn't, so I took my old hookup, (2wire) from my 89, rigger it up, (big wire to Bat+) and little to switched power, and bingo.

I have connected DK GRN to DK GRN for my coolent sens, but its still flat.. and I have no idea if it is the right wire from the c100 since i have no idea how to read that plug.. but anyway its the only left over wire.. maybe i have a bad sensor or something..
