Duraspark 2 wiring
I'm wiring up the new engine in my bronco and had a question. It has a Duraspark 2 ignition now, courtesy of my donor rig. It has two harnesses coming out of the Duraspark box, one going to the distributor and coil, and my question was where does the other go? It has two wires, one red, the other white. Does it go to the solonoid? My bronco Chilton manual doesn't have it in it. Can anyone help?

[updated:LAST EDITED ON 15-Dec-02 AT 09:33 PM (EST)]The white wire going to an ignition switch that has an extra contact for the white wire. The extra little terminal on the solenoid can be used like the other poster said, also. But you have to have a solenoid that has two small terminals. Some later models only have one. It makes no difference which way you do it.
I just noticed something. Don't try to connect the resistor bypass and the white wire to the same terminal. 12v would feed backwards through to the white wire and retard the timing all the time. I don't think I mentioned that this is what the white wire is for. To retard the timing while starting to make the engine easier to turn over.

The little terminal closest to the bat+ terminal is the S. The other little terminal is the I. It is only hot while cranking.

Thanks for the help. One more thing, though. The previous owner cut the red wire leading from the coil. Where does that go? The diagram confuses me with the ballast resistor.

I ran the red wire to the ignition switch. After a while the engine ran like the timing was out. It turned out to be a bad ignition switch. I replace the switch and all was fine. A few months later it has started doing it again. Where else can you connect the red wire?
