So need some help guys and gals I scored a tic tock tach which I'm currently converting to quartz but I tried to test the tach I have the old Mopar MSD box (see pics)that hooks right up to the original harness and has the wire on the side that goes to my aftermarket tach I tried no dice I hooked it up to that feed and it doesn't work would anybody know if I would still need the MSD adapter or do I just have a bad tach thanks in advance
