Question full voltage?

Bypassing the ballast resistor will not "short out" your orange box. That is all on the upstream "supply side". To short it out, you would have to do something to connect its downstream "output" to ground. But, you don't appear to be reading the posts. Several mentioned that running a 1970's Mopar ignition w/ full 12 V may damage your ECU (orange box), but your car so welcome to try, just carry a spare ECU.
