Ballast Resistor Wiring

I bought a new coil with a ballast resistor neatly attached to the mounting bracket. My intent was to neaten up the firewall while adding some killer spark power. What I did find was two 14g wires going into the resistor, and two 12g wires coming out. One wire goes directly to the coil+. The other runs the opposite direction across the firewall. I suppose I could leave the firewall resistor and splice off the hot Ignition wire running to the coil mounted resistor. But, not knowing the extra wires are running to/from, I don't want to start cutting (not having a diagram or any info).

Any input?

BTW it's a '64 Dart w/225 Slant
