Help required - Speed Sensor Wire

vindaloo · 17th October 2010, 21:34

I know the Speed Sensor Wire is a very fine Grey/White wire that is connected to the plug at the back of the instrument cluster but does anyone know where it routes to from there?

I need to know the best place to splice into it as I need to run a wire to Pin 1 of my audio ISO plug for the Nav function on my Becker 7945 Radio/CD/SatNAV unit.

This is absolutely a guess.....

The Hi-line system GPS uses the speed sensing in its calculations, so if your system was an Hi-line it will appear in the loom which plugs into the GPS/CD unit in the side of the boot.

It goes from there to the ABS ECU.

Thanks for the reply to my old post. In the end I didn't need the speed sensor as I fitted one of Sean's DD's.
