I believe the CJ2 uses the same ECT portion as the PCM to check temperature. To get into the diagnostic mode you push both knobs and hold them for 10 seconds until you see -00 on the screen. Turn the left (driver) knob until it says -12, then turn the right (passenger) knob and it will display your ECT temperature.

I haven't looked into the Cruise situation much yet, it's after I fix the ABS. The wire lead from the brown wire in the connector that plugs into the cruise control servo (has the cable coming out of it that goes to the throttle body), and had it connected to the grey wire of the fans. I believe (off the top of my head) that the grey wire is the low speed on the fans.
I want to fix the ABS and Trac control lights first because frankly it's more important to me. Also, I've heard that with the ABS light on Cruise can be disabled.
Thanks again for all the responses guys.
