There are three connectors. One is a double unit that can go in only one
place. The other two - both female connect to any one of the three +15
terminal spades which are mounted to the +15 terminal coming out of the
coil.

Other than pulling from one coil and plugging to the new one - nothing
is different - just that the tach doesn't work.

Thanks,

John
