2nd Gen Non-Engine/Transmission v10 gages in diesel?

Will a gage cluster from a 1997 v10 work with a 1997 diesel? Will the RPM still read correctly?

You won't have a wait to start or water in fuel light. Don't know about the tach, but I would think not.

the gauge cluster should be the same BUT the Hash marks will be wrong. They both have the same needle sweep but a lower indication on the diesel.

the diesel tach goes to 4K an the v-10 goes to 6K? if you put the diesel overlay in the V10 cluster it should work I think. otherwise all the diesel lights should be there and wired, you might have to install bulbs though

I guess my question is what will the v10 tach do?? Will it read correctly? I realize they are they same sweep, but if you command the v10 tach to read 4K then it should read 4k.

The Dodge tachs are driven by the PCM. The PCM needs to know engine speed as part of its normal functioning. It takes input from the Crankshaft Position Sensor (gas engines) or Engine Speed Sensor (Diesel) in order to do this. As one of many functions performed by the PCM, the PCM produces an output signal to drive the tach. The tach is merely a slave to this signal.

According to the specification section on page 8E-29 of my 1995 factory service manual, a V10 tach requires a 125 HZ signal from the PCM to read 3000 RPM. A V6, V8, or Diesel tach requires a 100 HZ signal from the PCM to read 3000 RPM.

What I take from this is that a V10 tach operating with a Diesel PCM will read 20 percent lower than it should. Thus when your engine is at 3000 RPM the V10 tach would read 2400 RPM. They may have changed the specifications by 1997, but I doubt it.

sounds like a v8 tach would work though
