HOW TO INSTALL CRACKEDBACK'S HEADLIGHT HARNESS

Try this analogy.

It's works like a water system with a storage tank separate from the well pump..
Join the tank and pump together with a manifold in between them.
The manifold supplies the main circuits that feed everything else. If the tank is at 12 psi, and the pump is providing at 14 psi, where is the water going to flow from ?

I get why you would tap into power from the alternator post, but if part of the reason of doing this is to bypass the bulkhead connectors it doesn't do that when the engine is not running. That is all I am pointing out. Did not mean to stir up a hornets nest.
