In the instrument cluster, usually at the bottom half of the speedo.
The cluster is the part that includes the speedo, odometer, fuel gauge, etc...
Disconnect negative battery cableTilt the steering wheel to its lowest position and remove the instrument cluster bezelRemove the instrument cluster retaining screwsPull the instrument cluster out,unplug the electrical connectors from the backside and the shift indicator from the bottom (automatic trans models) then remove the cluster from the instrument panel
Going through the same thing on a 89. Pull the front of the dash off above the steering column. There are 4 screws holing in the gage cluster. Undo them and pull forward, then disconnect the cable from the gage cluster. Note: the (speedo) cable is just clipped to the instrument panel a good yank is all that is needed to remove the speedo cable.
The speedo unscrews at the driver side axle, passes through the fire wall and is held to the dash by a rubber grommet. 5 screws takes out the insrument cluster bezel,then disconnect the wires on each side be4fore separating . Then 4 screws takes out the instrument cluster and there is the speedo. It simply lays inti the cluster when reinstalled, no clamps. Very simple. Installation is the reverse.
I have an 88 Jeep Comanche and have replaced the cluster bulbs and also replaced the whole cluster to a new cluster with a tach. You have to remove the dash trims (3 screws), then it will expose the screw for the cluster. Remove those and carefully pull out the cluster. It may not have enough slack due to the speedo cable and you may have The Cluster with a tach beside the Speedo plugs in just like the older one with no problem. Just make sure that the speedo cable clip that attaches to the new cluster with a tach fits the same or you may have to replace the speedo cable to match.
You cant Its part of the instrument cluster If you did the engine wont run
# Disconnect the negative battery cable. # Apply the parking brake and block the rear wheels. # Turn the ignition switch to the OFF position. # Shift the gearshift lever to the 1position. # Position the steering wheel in the full-down position. # Remove the two instrument cluster bezel screws. # Separate the instrument cluster bezel from the instrument panel enough to gain access to the electrical connectors. Disconnect the following electrical connectors: # Rear window wiper/washer switch # Rear window defogger switch # Hazard warning flasher switch # Power E-AT switch, if equipped # Security indicator lamp, if equipped # Cruise control ON/OFF switch # Headlamp switch # Remove the instrument cluster bezel with the switches attached. # Remove the four instrument cluster screws and separate the instrument cluster from the instrument panel. # Position the cluster to gain access to the gearshift indicator. Remove the gearshift indicator from the cluster. # Disconnect the electrical connectors from the instrument cluster and remove the cluster. # The installation is the reverse of removal.
The speedometer itself will work but you will need to take the instrument cluster apart and transplant the speedometer unit from the 92 cluster into the 87 cluster. The speedo mechanism is the same but the clusters are different.
There isn't a cable. It has sensors on the drive wheels that send an electrical signal to the instrument cluster via the computer.
If you mean the bulb in the dash indicating your high beams are on, you need to remove the instrument cluster. Depending on the year of the car, you remove the instrument bezel cover, usually a couple screws under top edge of cluster, then remove the cluster. These screws are usually 2 at the tope and 2-3 at the bottom of the cluster, then remove the cluster, disconnecting 2-3 harness clips and the speedo cable if not equipped with digital speedo. Bulbs plug into back of cluster. Change them all if one blew out the others are not far behind and not very expensive....
