For those of you running MSD boxes with a DSII did you have to install a tach adapter? I have a MSD Street Fire unit and the instructions say that I may need one, there is a listing of aftermarket tachs that will need the adapter and my sunpro is on the list. Has anyone been able to do without one?
I just used the grey wire with my sunpro tach and it worked perfectly fine. My tach was on the list as well saying it needed the adapter.
