I installed a msd 6al btm 12 years ago and hooked the small purple/black wire directly to the male spade terminal on the end of the box and the tach has worked perfect ever since.
no tach adapter was used.
Now having said that, today I'm installing a new msd 6al btm on another 930 the same way so will see if the tach works or needs the adapter. If it does i'll use the 8920 msd. I'll let you guys know how it turns out.

1976 carrera turbo
1979 930 3.3
1982 930 3.4
