what color ignition module to use

[raj]

   I have a 73 cuda and i have put in a 440. I have two ign modules and i dont know which one to use. The one i took out  of the car is chrome and the one i have in the box new is orange. I believe one of them has a higher out put. The car is stock with carb intake and headers. Thanks

Unless it has a Mopar Part # on it it could be anybody ECU , does it have 4 or 5 pins ?
the orange box is a good performance box for sure although the Mopar Chrome is a better ecu
