Hello, I have an 86 Vanagon and I'm having real trouble finding where the
tach-o wire is in the engine bay.  I've got an empty pin on my coil and it's
lonely!  Anyone know what color wire I should be looking for?

I'm trying to get this van ready for a long distance trip up northwards, and
I think a tach would be nice.

Thanks in advance!
