The early mopar ecu's had 5 pins in the connector the mopar performance and late ecu's have 4 pins. If you have all the wiring for the ballast with 4 terminals it will work just fine with either ecu. The extra resistive elment in the ballast and the extra wire in the connector to the ecu is just not used.
