Hi, I have an 2006 Ford XLT Ranger . The fuel gauge, temperature gauge , rev counter, speedometer,odometer, have all stopped working. I have checked all the fuses all are OK. The fuses were checked with an AVO not just a visual check. The problem is intermittent, It will be fine for a few days and then fail. I suspect a faulty relay but lack a wiring diagram, any advise is appreciated.
My 06 ranger is a 4 cyl model and I also am looking for a wiring diagram. Have you checked bulkhead connectors on the firewall for security, corrosion etc.? If you find the schematic on line please post the link. Good luck.

most likely problem for the fuel guage is the sending unit. The temperature sending unit should be easy to get to. depending on the motor, it is going to be a one wire connector going to it, most likely on the lower intake manifold. Once you find it. connect a jumper wire to it from the NEG battery terminal. It should peg out on hot, which would mean a faulty temp sending unit.

I'm dealing with the same issues on mine: check the speedo cable is properly hooked up on the back of the instrument panel and at the sender on the transmission. Check your electrical connections and fuses are ok for all the other instruments.
You may have a couple separate concerns. The fuel gauge if it is on empty may have a hole in the float. The speedometer odometer and trip meter is probably a broken gear in the speedo assembly. If the speedometer itself works it is getting a signal from the speed sensor.
