What are you trying to do? Hook up an aftermarket tach or get the original one fixed? The cluster I am looking at doesn't have a tach, but if it did, the tach would get it's signal from the PCM with a white/pink wire.

You might need to call the tach people and see if they make an adapter for the tach to wire in to your van. The PCM is the engine computer, and since it's a van, I will have to look up where it's at.

So I might have made too many assumptions about being able to hook it to the PCM. If you can get with the tach people, they may have a way you can hook it to the alternator, or somewhere else with an adapter.

It says that the wire ends in the harness for your Van, you may be able to dig it out and use it if they used the same PCM as is in the 2001 7.3L Diesel Excursion.
I would say no the signal is not at pin 5 on your cluster, pin 5 on your cluster is a ground wire.
Let us know what you find and good luck.

I think I may have posted the wrong information, what I posed was for a 2001 Van with a 7.3L Diesel.
If yours is a F53 Motorhome with a 7.3L Diesel then you do not have a female pin #19 in your PCM Plug and may not have the male one at the PCM either.
Sorry
