I'm sure there's a diagram somewhere on here, but I can't find it.
I'm putting a MKIII/IV steering column on my MKI, including the column stalks and ignition.
I've been poking around with a multi-meter trying to work-out the wiring, but it's a lot of work for little reward.
I have the MKI workshop manual which, of course, isn't much use for this task.
I decent photo of the diagram will do.
Otherwise it's off to E-Bay to buy the Haynes manual.
