The speedometer, tachometer, mileage, and gas gauge don't work. I've been told it would be wiring, and think that myself - but don't know where to look + I don't want to pay Jeep alot just to get it fixed if I could figure it out myself. I got a different dash for it, thinking that maybe the circuit board or w/e went bad or something but that wasn't the problem. So.. does anyone know a website that would display a picture - or even you giving me some advice on how to fix it would be terrific.

Re: Gauges not working..
Check your fuse box for lose wiring in the back and, check the fuses as well. if the problem still persist, then, check the cables on the back that run to the actual motor. these cables may have been severed due to age.

The "cluster" means all of the things you see under the plastic cover in front of the driver, the 'gauges'. The term is a reference to the 'instrument cluster' including speedometer, tachometer, fuel gauge, idiot lights, temperature gauge, everything. Get a second independent opinion since this is very unusual. Most likely you have a blown fuse.
Sounds like the body control module has gone bad. It has a relay that caries considerable current to all of these accesories and wears out. It can also be a solder joint on the circuit board where this relay mounts. Hope this helps, Robert
Located behind the instrument cluster
It is attached to the rear panel of the cluster.
input from battery is 10Volts, it regulates down to 5Volts
Any higher voltage inputed will overload the capacitors and resistors will burn,
Also check power distribution center, under hood upper motor area in drivers corner, check all relays and fuses.
Before you rip in to the dash check all ground wires, battery to ground, harness grounds, driver/passenger mid fram rail, Fuel sender is also ground to top of gas tank. IF ALL gauges do not work, that just leaves voltage regulator and/or cluster is malfunction,
there are rechargeable aa batteries that wear out over few years and have to be replaced behind the tach on some cars.. I just did it on a BMW and the tach started waorking again as well as the gas mileage indicatoor gauge
