http://www.msdpromag.com/pdf/8973_frm25079.pdf There's the wiring diagram. I just called MSD, and they confused me as much as their diagram. Not sure why they can't post up a diagram for those of us without crank triggers. Anyhow... Violet/Green from the 8973 to the same on the mag? What of the Brown/White wire from the 8973 that shows as going to the input lead on the mag? Mr. Canter, are you out there?
