MSD-How are you guys hooking up your ON-OFF switched wire ?

Man, You guys got me going now. Thanks for the ideas. I was just about to cancel this question, when the real racers showed up. You Guys!

Rocket got me thinking his way and I was wondering about possible voltage drop through the switch when rob-robinson87 jumped in and cleared that up and Abodybomber added another good idea all in 15 minutes. It's been a long dormant day.

Thanks for your thoughts, time, and the great pic.
