single, put it in the intake for best results, Ill let the others on here tell you which model to buy,( resistance etc) BUT I will say that temp gauge sensors were originally designed to check the DYNAMIC average water temp before the thermostat. Always use an IR gun on your intake to verfify your sender is in the ballpark.

I asked the M&H guys about this on a harness I had. I bought the extension harness that goes to the sensor that is mounted in the head on the drivers side for the temp gauge. The extension harness leaves the 3-pronged connector available so that you have both of them hooked up. They said that the 3-pronged sensor was also part of the TCS system. Here is a pic of the extension harness, it looks like the single wire on the bottom is what goes to the other sensor, so that's the one you should use. I haven't received my harness yet, but here is a pic of it from their web site.

I have at least two three pronged temp sensors. They look the same as each other. One used and one like new. Any interest in one of them? If so I can post some pctures later.

..Most definitly...

As promised here are pictures of the two sensors I have. I'm not sure when I got these, where they came from, how much I paid or what part numbers they are.

I do not have GM boxes for these.

Each one has markings just above the threads.

The NOS one is visually perfect. Markings read AC-85M-220B-253M. Asking $95 shipped to any continental US address.

The used one has some light wrench rash. Markings read AC-95M-230B-253M. Asking $25 shipped to any continental US address.
