You can put a brand new regular wire from the switch out to the firewall, and then go buy a Chrysler type resistor and mount it to the firewall and run the wire to it, and then out to the coil.

Got to use two of them because there is only .5 ohms restancice
got to use high heat conector
and mount new one out in the open

could that keep blowing modules
only takes about a mile to blow

on a side note and read a bunch of old post and fond your answer of the christer restior sevarel times

Do you think the wiring was messed with? The failure mode of a resistor wire is opening up, not shorting out, unless someone has re-wired the truck.

I am getting a voltage surge @ the coil + side
somthing is taking out ds2 module (cheap junk) but they have burnt 4 times in the last week

I wired a meter to the coil + and and a test light to the - side of the coil
ran fine till it started surge to 12 volts the the test light started flashing odd
and truck ran bad if i slowed it down the light flash pretty good but the module was toast still got the votage surge too
Pick up coil test good
and the coil test good
module bad

If stock appearance is not an issue, take a look at our one piece D.U.I. Distributor. We curve each on a distributor machine based on your engine combination. Please see them at:

Also, there is now an excellent installation article on the D.U.I. Distributor on the Ford-Trucks.com site at:

is it possible that your alternator is surging? lets say the resistor is supposed to lower 12-13 volts down to 8-9 volts. If the alternator was creating a surge your resistor may be reducing 16-17 volts down to 12. Just a thought as I agree that resistors dont normally short they open. another possibility would be a bad ground somewhere causing stray voltage to feed a higher voltage into your ignition circuit.
