Its been 3 years since I did it, cant remember if there was a wire there or not. If there is, snip it from the current harness and run new wire from transmission speed sensor connector to it. Good luck.

Thank you!!! I’ll keep you updated on the results! 🙏🏼

The mtx/atx pinouts are different for the connector to the cluster. Also your automatic car has a sensor at the diff to read speed while the manual cluster uses the speed sensor on the manual transmission. I bought the mtx speed sensor connector, plugged in it and ran the wires into the car, grounded one out on the crash bar [any ground is good] and the other I put in pinout # 19. It should now work.

 

Edit: you can find the pinout numbers in the R34 workshop manual on page EL19. If you don't have it, shoot me your email and Ill send the manual to you.

Thank you soo much!! I did forget to mention that the car was converted to manual before I purchased it. So I’ll take a look at the diff for that extra sensor just in case. Ahhh I see now.  I’ve looked at the manual and found pin 19!  So to be 100% clear, I wire directly to pin 19 and not just tap into the existing wire?

Speedo is now operational. Correct wiring is #19 input and ground out the other wire. I put the ground on the crash bar vertical support to the right of the stereo.

Appreciate the help gtsboy! 

How exactly did you do this? I have a r34 25gt converted to manual. Auto speedometer was working fine. Swapped for a Nismo GTT meter and now speed gauge won’t read. Would you happen to know how I can get the speed gauge to work?
