I think it's fine if what's discussed morphs a little..
especially if it's related.

yeah..you should see the green wire at T14 at the instrument cluster ..
but not in the black junction box.
If your non-tach 85  is different, I'd be interested to know.

Not hard to run a wire of course.

Thanks, David & Scott. I will have a looksee if my 85 donor has said green
wire. Worse case, I need to just extend the wire from the 84 with a tach to
the back.

Didn't mean to lead (no pun intended) the thread away from the subject
title.
