hello all
I am building a resto mod 1973 dodge charger Rallye.I am converting the car over to fuel injection.I have sent emails to Ron Francis and his suggestion is put a gM TBI set up ,uh no way,I have the complete engine and wiring harness that has the data link,ecm plug and this big oval grey plug that un hooks in the event of a engine swap or other mechanical stuff.I am trying to find a diagram of that plug to tell me the input side ,Mopar Performance wants 500.00 for a harness that uses 5 wires to hook up and your running,I want to see if i can make the factory unit work,If anyone out there has a diagram or can email me one would be greatly appreciated.thanks redrallye73

Call your regular mechanic, tell him what you're doing, and ask him if he can print out a wiring diagram from his Mitchell or All Data. Don't forget to definetly offer to pay him for his time.
