I have a 84 rabbit, i wanted to put a gauge cluster out of a jetta in it with a tach,(mine has the clock) would this be hard to do, where would you get a signal for the tachometer??
thanks
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?
I just wanted a tach for my rabbit, I was hopeing i could just bolt up a cluster with a tach and run wires?
is it not this easy?
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.

where did you find your tach at?
