Starter not disengaging?

Installing the diode in the circuit corrected the problem. This isn't an exact match with the factory wiring schematic. Incorporating the Mopar orange box ignition and the ballast resistor created the back current issue. The red wire from the coil to the resistor meets with the wire coming from the starter relay ignition post wire. Once the motor started a small amount of current was flowing from the coil back to the relay preventing the starter solenoid from disengaging. A lesson learned. One can think it's not wired correct. As the car sits it's wired correct with what's installed. I appreciate the guidance and hope this helps someone in the future.
