Turn that original ignition module over and see what color the plastic is that the wires go into. The new one looks blue. I bet the old one is green. If it is they are not interchangeable.
Yes sir, new one is a blue-ish color. Old one is black.

What month was your bronco built in?
If it hasn’t been painted over or removed there would be a certification label on your driver side B pillar above the striker post.
It’ll say what month.

Mine is a 75 also and advanced auto listed a brown grommet for it and it was only a 3 wire plus the two wire red and white plugs. Mines a 4 wire and 2 wire. Was curious if the aftermarket’s are sticking with the correct colors

Hey guys sorry for the late reply, been overseas on a contract. Was able to get a '75 ignition control module and changed it out. Fired right up. Thanks for the help guys.
