You do great work!
That mod was inspired by one of our AZ Pantera owners who had an electronics fail, and his starter started cranking (without him in it). The car went forward, jumped the curb, and rolled into a wall, stopping forward motion. The starter was still going, slipping the clutch.
He was able to reach in and shut things off instantly.
It was at that time I realized what a valuable mod a battery disconnect could be. I use mine all the time.
Obviously, all the Race Cars have them, so it may even add 5-10 horsepower!
