No it does not, it goes back to the wiring harness below and under the break booster.

That's good as long as it's connected it makes it's way to the right spot some times you can have a bad duraspark box on the fender well and they may have switched to the distributor they had (points) .. Just verifying you have a hooked up duraspark ..

The box can leave you stranded .. That being said buy a new one put it in and test if that was the problem buy another and take it with you where ever you go and toss the old one .. If it wasn't it take the old one with you where ever you go ..

More than likely, the starter is bad. Cables could also be bad. Perform a starter circuit voltage drop test to rule out connection and cable problems.

I agree with this post, it is most likely the starter. I would check the battery and starter solenoid first however it sounds like the brushes are worn in the starter and are not making a good contact.
