Broken down college kid

The push on wires (the blue and the green) connecto to two matching push on connectors on the alternator. It does NOT matter which one is which. The black with the "shroud" hooks DIRECTLY to your battery

When you say it won't run, explain exactly?

It does / does not crank with the key in start?

It does crank, but the engine does not fire?

If it cranks, does it do so "briskly" or normally, or does it barely crank?

Battery could be down, or you could have other problems.

Does anything in the car work, like lights, accessories, heater blower, radio, etc?

You have a shop manual/ diagram? If not, you can download one at "My Mopar:"

(in two parts)

These diagrams do NOT show the seatbelt interlock system, if used. I'd advise disabling it, not needed. On the relay, there should be two "yellowish" wires. Pull those out and hook 'em together.
