Forget about the coil, bypass, brown wire to the coil. Ignition 1 (ignition switched/run power) is present on the blue wire/wires in the engine harness. You will find these wires at one end of the ballast resistor, at one of the field leads at the alternator, and one lead at the voltage regulator. If the wire colors are not clear, disconnect the field leads, get out a volt meter and check with the key on. You will find only one wire that measures battery voltage there with the key on.
