Tach cluster

It might have some different warning/indicator lights at the bottom of the speedometer than what would be found in a pickup truck but those are easy to swap the little colored lenses if necessary. It would require changes to the wiring if used in an earlier year (73-77) pickup or any 73-87 that was originally equipped with a warning light cluster instead of gauges.

The air pressure gauges are probably quite popular with folks using air ride suspensions or like DBLSPRT68 said, can be swapped for a clock. That's something you can't do with the stock 10-35 series tach clusters because the small fuel gauge is located in that lower/left corner instead of in the bottom of the tach.

When you pull the cluster, get the 3-wire harness that plugs into the back of the tach too. The other ends should just plug into the fusebox and ground buss near the lower corner of the dash (near where a pickup parking brake pedal would be). And one wire goes through a grommet in the firewall. With a diesel engine, these tachs operated off a magnetic sensor that reads off the flywheel teeth. I think they can be converted for use with a gas engine by changing the calibration resistor on the circuit board.

Thanks for the info Ray. I didn't have much time to remove parts from it so I cut the tach wire as far back as I could reach, about a foot. So I got the cluster, AM/FM stereo radio, speaker, and the rear speakers & all wiring, sun visors, both complete doors, heater control, Ignition switch with key, dome light, and seat belts. All of the parts are in pretty good shape.

Thanks everyone for your help.
