need help finding a wire
THERE IS NO SUCH wire. Remember that the ignition switch is the ultimate source, the "headwaters" as it were, for switched power. All you have is
1...Accessory, which is hot in "acc" and in "run." It goes dead in "start."
2...IGN1 or "ignition run." Hot ONLY in run, it goes dead in "start."
3...IGN2 or "bypass" (brown). This is what supplies ignition voltage to the coil during cranking. Hot ONLY in "start" and it is a SEPARATE switch contact from the yellow "start" wire
4...."Start" normally yellow.....hot only in "start" feeds power to the starter relay
Tell us more about what you are doing. If you still run an ignition requiring a ballast resistor, you might be able to use to large rectifier diodes, run them off "ign1" and Ign2" and tie them together
You could also do this with a relay.
If you change to an ignition not requiring a ballast, just tie ign1 and ign2 together
Here is how diodes would work:
The "load" would be whatever you are trying to power. The diodes must be large enough to handle the power from the load. V1 would attach to the IGN1 terminal of the switch, and V2 would attach to the IGN2 terminal
If you don't have large enough diodes, or what to do so, you can use two smaller diodes to trigger a relay coil at the "load." Then wire up the relay contacts to supply the load your are connecting
