I did a quick search and didn't really see an answer to what I'm looking for. I will be running an electric fan in place of my old mechanical fan and I still need a way to control it.
My situation is probably a bit different than most as my '97 Cherokee has a 7120 head on it. These heads have a small (1/4"?) port on the back of the head for the indash guage. Anyone know of a control sensor that will fit in that spot?

I believe that hole is 1/4 pipe thread. Napa probably has a single wire sensor that closes at whatever temp you want.

Get this kit it works excellent. My elec fan turns on at 185 then when it gets to 210 my stock elec fan turns on,and also turns on when a/c is on
