Dash gauges ?

[Shredneck]

1992 4.0 ranger single cab speedometer, oil gauge, gas gauge all not working only rpms work. Anyone got any ideas of why or how to fix it ? Thanks

Damn my wiring guide only goes to 90, my guess would be a ground, since they all don't work and what are the odds of them all going out. Check fuses and all the connectorss, jiggle the wires. Hopefully some one else has some more info

Yes I would agree with a bad ground.
On the back of the drivers side head there should be a ground strap to the firewall, make sure it is there and clean and tight.

If you look here at Electronic engine controls 3.0/4.0 it has the wiring to check

Good read here about the speedometer

1992 Ranger still had a mechanical(cable) speedometer
