Is ecu needed on Msd pro billet plug and play

[Daniel J Thurston]

Hi I have a 70 duster 318 I am trying to figure which harness I want to use and what parts I still need. I can't find my Mopar ECU box thing... I have 2 wiring harnesses as well one with a ECU box plung and one without.

The distributor is a msd pro billet plug and play. Street fire wires With a acell super coil. I am not sure if this system needs the ECU box or not.
Also if not than do I need the ballast resistors as well or not

I'm not really a electrician so I'm out of my element here also when I had the msd installed on my 74:they had some type of aftermarket box like a relay or something between the batteries and the coil I'm wondering if they used that instead of balsat. Idk any help would be great ...

And if anyone has a diagram for me to follow you would be my hero. Thanks

If its true plug and play then no ignition contol box is required. What part number do you have?

There are a lot of MSD distributors out there. If it has only one plug with two wires, purple and green, it needs an external module. If it's something else, post a picture or part number for what distributor you have.
