The wiring was all pulled out when I got my 74 so I am not sure how it's supposed to wire up. I got a new coil, distributor, control unit, regulator, and I am in the process of installing a painless harness. The coil has two red wires coming off of the positive and one yellow off of the negative. There is one black and one red wire coming off of the distributor. The painless instructions shows a few options for wiring up the distributor and stuff, just not sure. Any help would be great.

What engine, instrument panel, ect? You might consider picking up a shop manual off eBay. Sure has saved my butt a few times already..

The original wiring must be hacked up because the original colors must be 14 gauge brown on + lead coming from ballast/ign switch and 16 gauge black traced yellow from ECU

I should have looked in my shop manual before posting.. You are 100% correct Nacho! All body styles are indeed the same.

Will this work? The original wiring was all pulled before I got it.  |

Got most of wired up, one more question. I have the two wires from the ECU (prongs 4 and 5)to the distributor with the connector on it. The distributor is aftermarket with a red wire and a black wire and no connector. How do I know which one hooks up to which?

What kind of dist? Actually the replacements pickup coils ( even Mopars originals ) are orange/red and black wires.  |

And if so, just searched an original diagram ( from an F body, but doesn't matter ) just to be sure once more the diagram I made is correctly "wired" on the ECU setup... should run to 4th pin  |
