MSD ignition

You have a + and a - direct to battery
The switched 12 VDC ,you use two wires, that were connected to the ballast, one is a switched and the other is the start wires, not sure what colors they are. I used a terminal strip to connect to.
the two bundles wires go to the coil.
White wire is the tack connection
Then you will have to connect the distributor to the wires that you are using. It has good instructions
Good luck
