No Speed Reading on AVCR?

[J@Y]

My AVCR just reads Zero on the display... All other outputs are fine.

I'm assuming the signal wire isn't connected up to the car loom, or is connected incorrectly. I don't have the manual as it was on the car when I bought it but from reading on here I see it's the White wire from the AVCR that should read the vehicle speed.

Can anyone tell me which pin/ wire colour on a makinen loom this should be connected to?

Also, my clocks read in KPH at the moment. Can I change this as a setting on the AVCR? Or if the car reads in KPH, does the AVCR only read in KPH?

Thanks
