Ballast resistor

[Fishthatkills]

Hey folks,
I will be doing an ignition upgrade from points to electronic on my 67 barracuda 273 V8. I have the ecu and dizzy, but need to know if anyone knows what Ballast Resistor I need. Part number from O'Reilly's or Mopar would be helpful. I got this dizzy from a FABO member, but no ballast resistor.

Thanks,
John B.

Are you going to use the 2 pin or 4 pin resistor?

It depends on how many pins your ECU has. I upgraded to electronic with a 5 pin ECU and use a dual ballast resistor.

Someone here can fact check me but you can use a single ballast if your ECU is a 4 pin.

Here is the wiring diagram I used to wire my car.

I will use the 4 pin ecu. A 2 pin resistor would be cool.

From O'reilly's

4 Pin--- RUE1

2 Pin---RU17


Take a look at their website I just got them off of it

This one should work,anyone else have an opinion?

I did this and eventually changed it out to an Accel electronic distributor, no resistor, as it was unreliable. I am not sure of the cause, but after it left me on the side of the road a few times and the orange box went twice, I was done. In hindsight there was probably some bad wiring causing the problem, but I am very pleased with the Accel.

Thanks to everyone for the help. What is the resistance of the "new" ballast resistor compared to the old one?

Not sure,the one in the picture is 1.25
