Could you tell me where the tach gets its ground from? out through which pin on the multi pin connector?

As I recall, it is a shared ground.
You can easily spend days locating this poor ground.
Many times I have been forced to remove the harness from a car, open every millimeter + breadboard + pin out. Just to find and repair a ground.
I can assure you; It is seldom worth the effort.
I suggest you ignore the factory ground.
Giving the cluster a fresh reliable ground is the critical factor.
