These pinouts have been the same since around 1989, and changed again to a new connector around 2002. THe subconnectors are used by things like changer, sat radio, aux in, etc. depending on model.

My connector has been cut away. How do I identify pin 13 by colors?

And about pin 10. I've seen other drawings where it is used for telephone mute. My unit (before it was removed) adjusted volume to speed and there was no teleohone. Is pin 10 tacho then?

Does anyone know if tacho is a pulse train?

And finally, what color has that cable?

Greatful for any help.
