They’re always centre positive so I use a polarity switching stub of cable (ebay) 12v is far too high, the factory ones do 14v and are labelled as 10 until under load. These cause unnecessary heat as well. The reglators get way hot but they don’t mind. I like the LM2940CT as oppose to 7805 with a 220uf cap on the output to set the 5v out. You can use a supply down to 7.5v then. It even works on 5v due to lower drop requirements on this regulator. no more massive heat
