72 dart electrical.

Depending which wires you're referring to- brown with the ring terminal is usually coil+, the others I can't really tell the colors... that bundle contains alt. field wires, temp. sending wire, oil pressure sending wire, ac clutch wire, sometimes an electric choke wire and carb idle pulloff wire, ign. 1 and ign. 2, ground wire to rear of head, among others depending on how it's equipped.
You really need to go to Mymopar.com and download the factory service manual with all the wiring diagrams for your car. It should be the first stop for everyone before they turn a wrench on their car.
