: '02 Amigos,
: I searched the archive, and lo and behold, nobody has a definitive answer to the following question. How to identify the plethora of wires running to the Ignition Coil. There is a double wire to the positive side, one of which I'm fairly certain is a resitor wire, since it had a .9ohm tag on it. The other which shares a plug is ????. On the negative side, there are two wires, one of which has an inline to the condensor. Now the questions. Which of these do what, and what are the ramifications to modifying your ingintion setup with a better coil, and electronics (eg. Petronix). Any experts? TIA.

The wires to the coil can be left in place for a coil/ or coil and pertronix upgrade I just did it on my 68 1600, and it works great.
If you want to install an MSD ignition you can only have the orange + and black - to the coil.
(those are the MSD wire colors btw)
The wires to the pos + side of the coil are from the igniton switch and the ballast resistor, and the neg - side is the dist and tach if it has one.
hope this helps, Brian
