No power to headlights

There's 2 reason why GM did that-one is that by using the starter lug as a battery junction you can have your charge lead routed from there to the junction. And, GM decided hey this is a good spot to also provide 12V batt power from too! Now, why GM would do that instead of just pulling everything off the common junction is beyond me. They certainly don't do it that way anymore so I opt to update my harnesses as such.
