Robert- The Firecore system is all this car has ever had in it. In order to use the RTR set up you need to modify the engine wiring harness by tying the blue and brown wires together and run a single wire to the coil. Then cut out the wires going to the ballast resistor and orange box. I contemplated swapping the engine wiring harnesses with my other Charger with the RTR system but that would be a PITA. I'm wondering now if the wire I ran from the splice with the blue and brown wires is heavy enough, not sure that would make a difference.I'll check the size of that versus the other harness and also check the splice tomorrow.

There was actually nothing wrong with the com cam fuel push rod I took out. But since it was out and I bought an NOS one I installed the NOS rod and will keep the other as a spare.
