To Ballast or not to Ballast?

ok, forgive my "re-asking" :D Just so I understand, if I went to this style of coil, I just need to eliminate the ballast resistor, correct?

Yep, and if you grab one out of a yard get the pigtail with it.
Also if you do end up with one and want to verify + and - let me know and I can tell you.
Mine is still out on the car, because I didn't take the time to remove it before the car show Saturday.

They also run a standard tach by connecting the tach lead to the coil negative wire just like the stock canister coils.

Gotta go now, but will be back later.
