Need help selecting ignition

[Ieatcamaros]

I still don't understand why it wouldn't work if the wiring was good. That makes it hard to say that this would work. I do know this: If you find a 12v switched wire, tap into that, and run it to the msd box you will have ignition. A 12v switched wire is one that has 12v(or whatever your battery's actual voltage is) when the key is in the ON position but has no juice when the key is off. Of course the same thing will work with the duraspark ignition too.
