Question, if the tach wire doesn't go to the negative side of the coil as per the service manual where do I connect it so my Rallye Tach will work?
The tach killing the ignition is not an uncommon thing with these cars...

1/ Check the grey wire for ground on it's way from the coil thru the firewall to the tach. It may have rubbed off the insulation somewhere
2/ If the wiring checks out, repair or replace the tach.
RTE sells replacement guts.

Thanks Dodji.  I'll check the grey wire out.
