how do i get this off?
How do i get the connector off the fan sensor/switch thats located in the passenger side head (at the back of the block)? I got half of the connector undone but have no idea how to get it off the sensor. How would I check this connector to make sure it is working (with voltmeter I mean).

Usually it is easier to get from by underneath the car. There are tabs on either side of the connector. Squeeze them and then it should be fairly easy to pull off. Not sure how to test it with the voltmeter.
BTW, what problem are you having?

Pretty sure my rad fan is not coming on. I never hear it running. I will drive in town all day and when I shut car off, it never moves. I don't have gauges yet so I can't tell the temp and I'm not too sure my idiot lights work. I have to change lower rad hose so might as well change the fan sensor switch as well.

Before you go out and buy the new fan switch, you can test the fan by unplugging the connector and grounding it out. For example, when I wanted to test mine, I had the key in the run position, but engine off (KOEO). I wedged a paper clip onto the connector core, and held it against the frame rail. When I did this, the fan came on. Note: you may have to wiggle the paperclip around a little.
After that, I decided to clip the connector end off and just ground the wire out to a nearby bolt. That way the fan comes on when you turn on the ignition. I will (and would recommend to) install a "manual fan on/off" switch before it gets too cold outside, though. I plan on using a fog light switch from a T/A, so everything looks stock.
If the fan does turn on, then the switch could be bad.
If it does not, then it is either the relay, the wiring, or the fan motor. You can test the motor, by unplugging the connector at the motor, and hooking up some jumpers from the pos and neg terminals of the batt. ONLY leave this on for a second, because the motor can not take that many amps for very long.
Hope this helps you. Oh, and if you do need to replace the switch, get this one:

With the key in the on position, if you ground that wire going to the temp switch on the passenger side of the engine, the fan should come on. If not then the switch is probably bad. Could be other things also not causing your fan to not work.

The foglight switch idea sounds like the way to go. Also you might want to install one of those aftermarket gauges sets that have temp, volts, and oil pressure because i've never felt real comfortable with idiot lights.

If mine had just the warning lights, then I would definetely install aftermarket gauges. They will be more accurate then even our factory gauges.
If/when you are ready to do the fog light switch idea, let me know and I can send you what I have as far as the wiring for it from the relay.
