Cigarette Lighter Addition

Hey everyone.
Say I was to add another cigarette lighter 12v port to my Tundra, and I don't want to splice it to an existing cigarette lighter's wires, where would I wire the new 12v port to? Are all cigarette lighters in the Tundra wired to some central place? How would I add another fuse for the new lighter/would I need to?

 

There are no cigarette lighters in the 2018 Tundra, just 12 volt sockets to supply power to your electronic devices. Not trying to be a smarta$$ but when you take a look at the wiring on your 2018 you will notice that most of it is probably 22 or 24 gauge which is very thin and will not allow you to power something (like a lighter) with a fairly high amperage draw. So, if you really want a lighter you should probably run a 12 or 14 gauge wire directly from the battery that way there is no chance to damage the factory harness.
Everything is CAN Bus now and wires pretty much just need to transfer a signal. You can even look at the wires going to the ignition switch, they are tiny and just carry a signal to a relay.
