Hmm lets see if I can be some help. I used the cigarette lighter 12V and tied the ground into one of the shifter bezel bolts. Autometer tells you to ground the guage close to the sender but I grounded the sender on the batt. and the guage works fine. Hooking up the sender presented a problem to me though. I didn't want to drill through the stock waterneck (piece that holds the thermo). So I bought a chrome waterneck with a 1/4" threaded opening already in it. That costed me $20 and looks nice . The other option you have is to use a t-fitting on the ECT sensor that's right next to your fuel rail. If you buy another water neck, the autometer elec. water temp guage comes with an adapter to get the sender into the 1/4" hole. Use teflon tape on this and your set

I agree with everything that blueneonman said, except for the T-fitting. Unlike pressure sensors, temp sensors should always be in the circulating flow path of the coolant. If you put in a T-fitting, you will be an inch or so out of the water flow. So, either buy the water neck with the bung, drill and tap your stock water neck, or sacrifice the use of the stock temp gauge, and put the Autometer sending unit in its place....
