The tach signal wire should be white/pink.
Check the other tach thread just couple of posts down.

Early tach wires (~pre-'90) were DkGn/Y. '90-91 were Tan/Y. '92-up were Wh/Pk.

A Haynes manual ($12 at most parts stores) has the diagrams.

Don't show me no stinkin Haynes Manuals! I have the $20.00 Haynes manual and it does not show any Tach connections for an 84 B-II. Does Chiltons still make manuals? I'm still trying to get my New Tach working. I should have bought factory manuals
