hi guys.....or girls,
i've just purchased a japanese imported 1996 liteace noah ,2000 cc fuel injected van.
it has most of the specs wanted but no tach.
i've had some electronic work done eg. alarm etc.
i supplied a generic type rev counter and asked for it to be installed, but when i went to pick up my new toy was told it could not be fitted, due to the fact that the electronics on this van........twin coils, i think do not supply the required signal.
they told me i needed to find aq low level input type rev counter.
i went to a few places, but as yet have not found one of these beasts.
new zealand is a very small country i know, so hey any help out there in the real world ?

if you can find it, there'll be an output from the ECU to drive the tach. If you connect into the twin coil setup, it should work, but might read incorrectly (double or half). Some later tachs are programmable- tell them how many pulses/rev, and they work it out from there.

So best bet is to remove the instruments and look closely at the pcb- one of the terminals might be labelled tacho... I was fitting a tacho to my wife's Corolla a while back and found the tacho feed wire went the whole way to the back of the instruments, even though the cluster didn't and couldn't include a tach. The pulse wire on the Corolla was black IIRC.

What about getting a cluster with tacho from a breakers?

On the Toyota 2c Turbo diesel engine there is a pulse generator on the diesel pump.How does one connect a rev-counter to this pulse generator and what rev-counter should I buy?

Well, one out of a toyota cluster for preference as the pulses wil be correct. VDO do tachos for diesels that interface with the "W" terminal on the alternator. Don't know how the pulses compare tho.
