I just installed a procol transmission temp gauge and its a no go I THINK I DONT KNOW HOW LONG YOU HAVE TO DRIVE BEFORE IT SHOWS A TEMP?? So my question is the gauge it has a T and a B on the two prongs so I took the T to the tabe on the probe and B to Ground did I do this right?

 

I got it working it needed 12v to the B prong!
