Volt Meter Mod - How to Undo?

Hi all,

I'm in the process of returning my mk3 to stock (never in a million years would I thought I'd be doing this), and in doing so I'm trying to undo the volt meter mod that was done prior to my possession.

Its a 92 turbo automatic, and at some point the previous owner replaced the boost gauge for a voltmeter from an NA model. I do have a spare turbo cluster with a boost gauge which I swapped but it still reads like a volt meter.

The boost/ pressure sensor is plugged in on the drivers side engine bay.

What else is modified/ swapped for this mod that I should be un-doing?

Also, I am aware that an aftermarket boost gauge is favorable but I prefer to put the car back into its original state as I have another supra that I'm modding for fun.

Any help would be appreciated!
