I recently installed a cut off switch in my ‘52 3100 and did the same research thru Google you mentioned. I decided to switch the negative, reasoning that I didn’t want 12 volts positive under-the passengers seat. on the pros side, it was easier to access the negative terminal for my setup.There’s pros and cons either way.
