Yeah, I got the new cable and switch coming yesterday. I just thought it was strange to not have at least a "off" switch from the factory, even with a single battery. The more I have been around performance boats, the more I thought about "why don't I have a switch" and then my mechanic could not believe it when he hopped into the engine compartment. In addition to the switch we are also going to re-rig some other items and hopefully clean up the wiring.
I will post some pics of the new headers, serpentine set up and battery box when we get it back in the boat.
Thanks
