Been putting it off long enough - Really need help with my gauge

[105-1006199262]

Yeah, i know this is like the 1millionth thread.  I need my water temperature gauge in TODAY (It's 100 degrees outside).  I tried tapping it into my old sender but the gauge moved but didn't even go above the bottom line at 100 degrees (Does a cold car's water temperature be less then 100 degrees? I don't remember how hot it was the day I tried this, maybe I should have warmed the car up).  Anyway, where do I put the new sender?  I think someone told me to put it in where the radiator line is going into the thermostat? Does this mean anything to anything to anyone? I don't know shit about the lines and shit coming from my radiator so if anyone could be specific as to where this is that would be great.  If not I'm gonna try the stock sender wire behind my gauge cluster against and warm it up.

Nevermind, I toiled and fiured it out.  No thanks to you.
