I don't have my instructions; however, I installed mine earlier this summer. The coils themselves do not have polarity, so you can connect each either way. Each coil needs an ignition on power source and a wire that runs to the distributer.
On my bike ('77 CB750K) the ignition power supply is the black/white wire. Each coil gets its own connection to the the black/white wire.
The blue wire gets connected to the coil that fires the 1/4 cylinders and the yellow wire goes to the coil that fires the 2/3 cylinders.
