The tach wire does not go through the 14 pin connector. Follow one of the white wires from the CD unit (there are only 3 wires going to the CD unit - 1 red and 2 white) to a white plactic connector near the CD unit. The black/purple tach wire should come off of this connector and run forward from there straight to the tach.

I have Beru wires on my car with MSD - no issues.

I have a complete write up on MSD installation for a M.Y. - but it's not near me right now. I can send it to you later today if you having issues.

Thanks for the info on the tach wire and also the Beru wires. I've got a few write-ups on installing an MSD system and some photos etc... all from the archives here. The wiring appears straightforward - the MSD directions are pretty good too. Mounting the beast of a box may be my greatest challange. I've got an external voltage regulator and rear window relay to deal with. That's my goal this afternoon - to get the mounting figured out.

Thanks,
Tom

Up and running! I installed everything last night and I seem to be good to go. The wiring was not too bad, I found the tach wire and it works. After re-adjusting my valve adjustment from over the winter, a new rotor and cap, new plug wires and the new MSD CDI box, its seems to be running really smoothly. (hopefully I didn't just jinx myself for my 5 hr. drive tomorrow). I've got some tidying up to do w/the wiring and elect panel in the engine compartement, but as it is now, it works and will get me through - even if it's not the prettiest. Also, I checked the battery voltage while running and it seems good at 14.5V. Hopefully that's the last electrical issue that I'll have to deal with for a while.

I'd love to know what caused my issues - whether it was something I inadvertently did or if something just wore out and quit. I plan to do some more investigating next week when I have more time.

Thannks for all the help,
Tom
