Running factory electronic ignition. Jumped white wire to battery to get it going. What do you suggest as a source for the white wire?
Thanks,

Maybe if he stayed off the crack he could figure it out
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

All you need to do is use the run line and the start line, tap them both through a diode and use that for your connection.
It is not rocket science.
Use the diode to prevent back feed from one source to the other.

Yep, diode is the easiest way.

Thanks Supercuda,
John, thank you very much for the drawing.
Did a little research on diodes and kind of getting it now. What diode would you recommend I get?
Thanks, nd65 1N4000 series are great for this. (1N4001, 4002, 4003, etc) and you can buy a bunch for a dollar. Craig

I get it now!!
Ignition 2 is the start mode and has 12 volts while cranking (brown wire).
Ignition 1 is run mode (blue wire). It has 12 volts when you let off the key when the engine starts.
The diode is basically a check valve. It only allows current to flow 1 way.
The diode gets wired from ignition 2 to ignition 1. This will allow 12 volts from the ignition 2 start (or crank) mode to flow to ignition 1 run mode. When the engine starts and you let off the key the diode (or check valve) prevents the 12 volts from ignition 1 from flowing back to ignition 2. Thus, ignition 1 always has 12 volts and the Fitech is happy. Correct... the Diode keeps working the ballast to the coil in run correctly with the decayed power. there was a nice discussion about this couple of months ago. A relay can be used too allong with diode, but makes a bigger and "complex" installation. Not required if the source needed is mainly just for triggering, and not for sourcing more than the stock system

I'm wondering about the posibility of a modified ballast to hide this diode jumping job, cuting the ceramic on back with a dremmel enlarging the groove and solding to the existant ballast ends on groove... would be an interesting job!
Of course, prongs will need to be labeled to plug Ign 1 and 2 on the same position allways
