Need Ideas from the group.
Purchased and planning to install master power cutoff switch with removable key as well as jumper terminals. My thought was the jumper terminals in the trunk but unsure about the master cutoff.I know many install between the seats on the rear wall trans piece but unsure if there are better Ideas. finally interrupt positive or negative? I want to say positive but that would allow the engine to continue to run once started..

Thoughts from the group?
