need a bit of help here.

Hey guys.. really been a while. Anyways,I bought a pro sport coolant temperature guage. And I have a diagram, that gives me color code. Except, I seem to have wired everything an it doesn't read my temp sensor. I checked the sensor with a multi meter at 20k. And from 2.89, It kept counting down as the car cooled down. Any ideas on the real way to wire her up so it works?

I can't be for certain, but the Prosport gauge probably needs its own specialized temperature sender. Not all temp sensors are created equal. The resistance @ specific temperature is different for each sensor pair. You may get the gauge wired into the factory sensor, but I doubt the resistance output from the OEM sensor will transfer over to an accurate reading on the gauge. You will probably have to source a replacement Prosport sensor. Sorry, dude.

Well that explains it. I was going crazy for weeks :/...

He is correct. I bought 3 new gauges and sensors from prosport and they have held up great so far.
