MSD "ready to run" system

You didn't tell us what you are working on. But you did mention points. So just connect the two ballast wires together, and use the old coil + wire to feed power to the new system. No need to run new harness.

Sorry, should have given more info! 72 340 presently with a new ECU equipped engine harness. Original car came with a 318 with ignition points. I discarded to old brittle harness. Not knowing at the time I was going to upgrade to MSD system. Was hoping to rewire the new harness vs buying another points equipped one.
