I believe the 74 Midget went to a 1 wire tach that was connected to the 
neg side of the coil.
If you have a 2 wire tach (2 white wires that is) does your new harness 
have the 2 white bullets for the tach?
If so, the tach change must have been late in 74.
Kevin!! You have a few 74s. Can you confirm?
A quick check to know if it's a 1 wire tach is the face plate screws are 
verticle instead of horizonal.
Charlie, that spade connector on the can is just a ground but it's a 
good idea to run a new, extra ground to that spade. Otherwise the tach 
is only grounded via the black wire on the thumb screw which is barely 
enough ground to light the dash lamp.
