Key on and cranking power wire?

dragbaron said

That's what I originally thought, but to have two cars in a row where the brown wire doesn't have power in the crank position made me think that maybe I was missing something.

I still need to go out to the '71 D100, that is the next magnum swap, and see if I can find a crank position power wire.

ALL older Mopar ignition switches work the same, unless they are defective

1...You have power in...............

2...You have ACCESSORY power out to the ACC fuse buss and is hot only in run and ACC

3...You have the (usually dark blue) "run" (IGN1) which is hot ONLY in run, not start.......

4...You have the (usually brown) bypass (IGN2) which is hot ONLY in start, not run. This is the one goes to the coil +

5...You have the (usually yellow) "start" wire hot only in start and what feeds the starter relay

The yellow and brown are drawn wrong in the 73 book, maybe others. The 73 diagrams suggest that yellow and brown are connected. THEY ARE NOT. They come off separate distinct switch poles in the ign switch, otherwise they would backfeed.
