So i been doing a lot of researching and looking thru old posts about adding a vw cluster with a tach to run off W terminal,. i am still confused as to what i actually need to do, i have an 84 jetta TD and a cluster from an 86 cabriolet, how do i make this work, and how do i swap the glow plug light into the cluster,
yes i have searched and just found a bunch of ramblings, i need to find like a nice step by step, with pics. anyone help? thanks in advance!!

just ploping in a gasser tach on the diesel W terminal wont work out very well.... the gasser tach needs modifications to read the w terimnal signal properly.

There is another alternative and I have been thinking about it myself. There is a guy at 4crawler.Com/Diesel/CheapTricks/index.shtml who has made a regular gas tach. work on a diesel using a photocell in the timing belt cover with the breaker mounted on the injector pump pulley. He has a kit for $40 to do this and other options including a tach as well. I don't know if he still sells them or not for that price or even at all though but his site is still there, again I don't know how to do the link post thing. It really doesn't look to complicated and you can use about any tach you want. I'm gonna look into it myself after I get this motor in, Spring if not sooner
I did the circuit on 4crawlers web page. Purchased the parts from digikey. Enough to do a few of them since a couple of friends wanted to try them too. With the 4 crawler circuit it mimics a gas tach signal so I can use regular gasser shift lights and accesories. To me that was easier than reworking the tach. I rework surface mount soldered boards at work so the through hole soldering and circuit was easy for me also.
I was going to post the link, but it's the same one you have, and it worked for me. :?
clean out cookies on computer? or maybe a hic-up when you tried it earlier?
I assume y'all read the end of the FAQ Gas tach conversion where jimbote describes how to add a Ford probe to the crank along with part #. No rewiring required. Cheaper than the optical sensor that Roger Brown uses.

Hi Andrew. I read that too, but at first I could not see where is shows how to wire the Ford Hall Sensor... Then I read the entire thread and saw it is so simple it did not need a diagram :-) I searched the web and found one reference to the cost being less than $10 for this part !
if I would have known about the Ford part over a year ago when I did mine, I would have gone that route.

I just read about the [jimbote] gas to diesel tach conversion and that looks by far the cheapest and least complicated method yet. Just one question, it will work with most aftermarket tachs won't it :?: This really looks like the way to go so I might as well weld those 2 nuts on the pulley now while the engine is out and look for a low rpm tach. I guess the in- dash tachs for the Rabbits are petty high arent they, and then you're not sure they work till you get them. I just hope it will work with a small VDO, Sunpro or something in that range for he T/D Rabbit.
