Thanks, you got it exactly right! Before I read your reply I had called M&H auto wire who manufactures this harness and they also said that the braided wire is a resistance wire that takes the battery volts from 12 something down to 9.5 volts for the distributor...so it will get warm to very warm.

They also verified the extra black wire is for trucks with guages...this particular wire is for the amp meter and it should also be connected to the main post along with the positive wire coming from the battery.
