I like the idea of swapping in a GM HEI module, and getting rid of the ballast resistor. The module part I understand. However, my ballast resistor ('73 Dart) has four seperate connections on it with four wires (dark blue, blue/yellow, brown, and green/red). I don't have a wiring diagram, so how do I rewire these wires to get rid of the resistor?
Thanks!

Pull the resistor and jumper both sets of plugs with two wires.

Okay, so this ballast resistor obviously has two resistors in it. What I think your saying is to pull the wires from each end of one resistor and put them together, then pull the wires off each end of the other resistor and do the same thing...right?

im prety sure the resistors go straight across

Piece of cake. Connect top to top and bottom to bottom.

Then if you want to get all OCD on it like me, you can completely eliminate it from the wiring harness altogether like I did, but that was a good couple hours worth of work pulling old wiring out, running new wiring and soldering all the connections.

WOW
Somebody needs to post a picture. Im even getting confused and I have a single and not a dual????

I just took two 2" lengths of 10 gauge wire, put male spade connectors, and plugged them into the connectors that plugged into the ballast resistor for a jump across, and wrapped it with tape so it won't come apart. Seems to be working.

Found a wiring diagram. So, it appears that one side of this two resistor ballast feeds the Mopar ECU, and Electric Speed switch, and a Throttle Position solenoid.

Since my car doesn't have the speed switch or position solenoid, and I will be ditching the ECU....why can't I just eliminate that circuit, and just bypass the circuit from the starter switch to the coil?

Seems this second ballast circuit was only added to feed the ECU anyway.
