Do you have a 4-cyl or 6-cyl?
I installed some VDO electric gauges. They are not hard to do at all.
I'm not sure where the 4-cyl temp gauge is but on a 6-cyl it's at the back of the head nearest the fire wall on the drivers side. Pop the cap on your radiator before pulling out the temp sensor. Some fluid will come out but it will stop.
As for hooking it up, the gauge should come with instructions. You'll need a wire to the sensor, a power wire for the guage, a ground wire for the gauge and a power and ground wire for the gauge light. You could cut the harness for the OEM/Stock gauge but I wouldn't suggest it unless you are going all out with a full set of new aftermarket gauges. Or you could use those taps to tap into the sensor wire and ground and power and light wires. Or just run all new wires. What ever you feel comfortable with.
If I have the option, I'd like an electrical gauge, but if not, I'll wait until I can find an electric one. The jeep is a 4 cylinder. Eventually, I'm gonna get that autometer gauge cluster made for yj's and install ALL new gauges. For now, I just want the temp gauge so I can see exactly what temperature I'm running.
