The signal is from the W terminal on the alternator. It is usually stamped right on the alternator casing.

Are you planning on installing the complete mk2 dash?

The diesel tach and gas tach have different circuitry because the signal from the alternator of a diesel engine is at a completely different rate than the signal from an ignition system on a gas engine.

There are various conversion techniques... changing the on-board components (ie parts and soldering), a signal conversion box, and of course finding a diesel cluster rather than a gas cluster... for Rabbits a bit of a holy grail.

Search here and at www.vwdieselparts.com and you'll find lots of discussion about the conversions.

Me:  I bought an aftermarket VDO diesel tach for my Rabbit truck... worked very well.

Local gauge store ordered it in from VDO... here's a pricey example from eBay that lists a VDO part number:
