Jerry, I enter the truck in AACA shows, they frown on non-stock parts. In an effort to hide the disconnect switch; I looked and I think that I can build a bracket to mount the switch under the battery tray/frame. Cable would come off the top of the battery, loop down to under the tray, go to one side of the disconnect and then go from the other side of the disconnect to the stud on the starter. This switch is meant to be used on the positive cable, correct?
