got a msd-5, 4 wires out
black - ground
white - connects either to the breaker points, or to the output of an electronic ignition amplifier. this connection is made on the outside terminal of the plastic spacer that is attached to the negative (-) side of the coil.
orange - connects to the negative (-) side of the coil, on the inside of the plastic spacer. this is the only wire that makes actual electrical contact on the coil (-) terminal.
red - connects to the positive (+) side of the coil.
