Ever since I converted the Westy to the 1.9 TD I have been without a
tachometer, as some of you know, the diesel gets it's tach signal from the
alternator speed, which is why the gas model's tach won't work. I finally
located an instrument cluster from a 1989 Jetta TD. The tachometer is
externally identical with the Vanagon unit, so it screwed into the housing
perfectly. The only fabrication req'd was to get the proper faceplate. I
used the top 2/3 of the diesel tach faceplate, and the bottom 1/3 of the
Vanagon faceplate, screwing them to the housing with the diesel one in front
of the Vanagon plate. (used sharp tin-snips to trim each one) This enabled
me to use all the original Vanagon gauge layout. Voila! Engine speed now
known! Looks factory unless you look real close for the faceplate trim
lines! In the process of getting the proper gauge cluster, I ended up with
an extra from a '94 Golf/Jetta TD, if someone needs that let me know.
