Duraspark ignition module

[rjcruz27]

Trying to figure what module I have and if it will work with the duraspark II harness I got from painless

 

[rjcruz27]

Sorry here’s the pictures. My issue is my module appears to be missing a prong on the 3 prong plug. Where is the best place to get one?

Go to your local auto parts store and get one with a blue grommet. They are supposed to be the best. Don’t think they are very expensive.

My issue is my duraspark ii harness I got for it has more wires than my originals. Is that okb

I thought the Painless (and probably any other brand for that matter) were designed specifically for the Blue Grommet models. Do you have the instructions for the harness to see what it says about it?

In the case of yours, clean off the plastic strain relief there where the wires exit the module and see what color it looks like.
What year is your Bronco?

As for the missing wire, most of the models have only two wires in that connector, even though there is room for three. Some actually did have three, but most did not I believe.
As for the orientation, I think it's an odd one which might indicate a non-blue model.
The bottom line though is if your new harness does not match up to the existing module position for position, it won't work. You need to look at the plug orientation and wire orientation.
But I bet the new harness is expecting to be used with a blue grommet model.

Maybe some help?

 

[rjcruz27]

So based on what you guys are saying I just need to take the connectors apart and put them together color for color? It’s. 1974. Where is this grommet located. What is the easiest fix?

Also if I use the harnes there are still all the wires from the original harness. What
happens with them?

 

[rjcruz27]

There’s a black wire and a black/green wire in one connector and on the 4 wire side there’s a purple,orange, white, red. Those don’t match any of those diagrams

Well woops, no help then.

No. It means you need to buy a "blue" module to match the new harness.

It’s. 1974. Where is this grommet located. What is the easiest fix?

The "grommet" as it's known is actually a wire strain relief, and it's the plastic block where all the wires come out of the module and go to their connectors.
In your pic it's mostly whiteish under all the old age. See if you can wipe that area down and determine it's original color.
The color/type of module can probably be determined by the orientation of the wires too, but I don't have the patience for that and it's so easy to go by the color of the "grommet" anyway.

Also if I use the harness there are still all the wires from the original harness. What happens with them?

What original harness? You made it sound like you have both a Painless chassis harness AND a Painless Dura Spark harness.
If correct, you don't use any of the old harness.

There’s a black wire and a black/green wire in one connector and on the 4 wire side there’s a purple,orange, white, red. Those don’t match any of those diagrams

Very likely they don't match because it's not a blue module
You don't need to worry about the wire colors here because you're not going to be using that old module. At least not if you want to keep things simple.
Yes, you can likely (but not guaranteed) re-pin the connectors, but only if the new and old connectors are keyed alike. Can you insert the new Painless connectors into the old ones on the module? If so then if you can figure out how to remove the wires and re-orient them, go for it.
But I would not bother. Just spend the 30 bucks on a new blue module.

Or better yet spend the bigger bucks for a Motorcraft unit, or go to a junkyard and see if you can find a blue module that looks original from Ford.
Paying for the cheap ones is a crapshoot with the quality (or lack thereof) of today's parts.

Awesome got a new blue grommet from autozone. Plug and play to the module,coil, solenoid.

What do you do with the remaining wires from the painless harness that go to the engine bay. Anyone have picture of their ballast resistor set up with a painless
