It has a spider in the middle and will have one in the
rear diff to in the next few weeks too!

I thought the mechanical/electrical feed on the tranny 
drove the speedo? I even remember pulling the electrical 
sender from the 200q20vt tranny and installing the mechanical one.

The rev counter is fed from the coil, except I have 4 too many.

Anyway keep the replies flooding in....

cheers, Mike

Any particular reason you don't want to stick with the mechanical feed
from the tranny?  Or have you swapped in a Torsen?

I am finally motivated to complete the coil-on-plug engine conversion in
my '84 ur-q. I had a 3B setup working perfectly but for some depraved
reason decided to convert it to coil-on-plug. During the conversion an
RS2 turbo, exhaust cam, MAF injectors and 944 turbo intercooler were
added. So it is finally coming together.
Any ideas on how I get an RPM signal for my '84 ur-q analog tachometer
from an AAN coil-on-plug engine/wiring loom? Is the tachometer signal
pin 40 on the ECU any good?
cheers, Mike
