Ignition Module Question

[66Bronc]

I have installed a 200 inline into my 66 bronco. This motor out of a 1980 ford fairmont. I assume to have the original duraspark II distributor. Since old motor had points, i bought what i thought was the right ignition module from NAPA per reading other posts. However, the plug in does not match? This distributor has 3 wires going into plug, orange-purple-black. This module 4 wires including a green?
I thought about splicing and not using the plug, but what does green wire do? Should i take this module back? this is one they told me would work?
Any insight is appreciated.

The dizzy sounds correct. What car did you use to get the module? I would use 76-77. Earlier could have been other versions and later could have got into computer stuff depending on the models.

8) the green wire from the module goes to the coil negative post. check out this site for wiring the module;

Hey thanks for the Mustang Steve wiring diagram..Looks like i just have a different plug for whatever reason. Probably not worth aggrevation trying to return the one i got to find one w/ plug that matches.. i'll just splice the wires vs using a stock plug connector. Thanks again Ford Six Forum!!!

The Mustang Steve wiring diagram was a life saver!!! I just spliced wires from modue to Dist and she fired up on my second crank. Thanks
