Thats what i was thinking but im not sure if its 1 pulse or 2 pulses and im trying to find the SR20DET wiring diagrams for the S14 but no luck so far.

The Altezza VSS is out now and the SR20 VSS and box are in with engine running and driving perfect just the speedo catching me. Some of the Altezza loom still present but not on the VSS side.

Obviously there is a difference in the output from the SR VSS compared to the Tezza but i dont know what it is or how to check it.

Its the SR20 gearbox which has a speed sensor but i think it operates on 2 pulses as opposed to the altezza which uses 1 pulse. Im not 100% sure though.

Does the Altezza have a speed sensor mounted on the gearbox also??

Is that sensor normally wired straight back to the back of the speedo or does it go through the ECU and then an output from the ECU to the speedo??

Hi mate, the RPM is working fine its just the speedo that i cant get working. Any ideas on that one?? I'm not sure how the altezza one works either. Any help is appreciated, thanks again

Hi Lads,

I have an Altezza with an SR20DET from an S14. I am trying to get the original altezza dials to work with the S14 speed sensor but no joy.

Does anyone have any ideas what the problem could be?? I don't have the wiring diagrams for either which is a bad start but i'm struggling here big time!!

Any help or suggestions would be greatly appreciated. Thanks
