[DeTomaso] Tach adapter with ready-to-run MSD distributor?

[MikeLDrew at aol.com]

Hi guys,

I am trying to help a friend who just fitted a new distributor and lost 
tach function as an incidental result.

I know that with a conventional MSD ignition system (with external box), 
you must fit a tach adapter to get the tach to work:

However, he installed a 'ready to run' distributor:

Do these, also, require the tach adapter?
