I just purchased a roller 302 engine for a 65 Mustang fastback project I am working on. The motor was pulled from a running car. When I got the engine on my stand and popped off the distributor cap I saw that it appears to have a type of electronic ignition in it but I have never seen one like this before. I can't see any part numbers or brand name. I have used the Pertronix ignitor kits in the past but this appears to be something different. I didn't look how the distributor was wired before the previous owner pulled the motor so now I am scratching my head on what this is and how it is wired. There are 3 wires coming from it that are orange, purple and black. Obviously the black is most likely a ground but I am unsure of the routing of the others. The number on the side of the distributor is 12127 which dates back to 74-77 but obviously these units had points in them originally. Here are some pictures of the distributor:

 

the black is prob ground the orange is probablly 12V and the purple may be for a tach??
you can get a hei distributor off ebay with 8 mm plug wires to your door for just over $50. thats what I would do.

 

thats a Ford Duraspark Distributor.Do a google search, theres a lot of information on them and they are pretty reliable and a cheap alternative to a name brand.

Wow, this helps a LOT!! I knew someone on the forum would have to know what this was and luckily I was right. I will do research on it so I know how to wire it correctly. Thanks a bunch!

 

You'll need the dura-spark computer also to make this work. I have had experience with the coil (blue object) experiencing an open which leads to a no- start or quits after running 1/2 hour complaint. FORD made millions of them and I agree they're a pretty solid unit. Also used in 4 and 6 cyls so make sure you have one with 8 poles on the reluctor

 

Do I have to have the dura spark computer or can I run this with a MSD box?
