cigarette lighter question

I'm rewiring a 68 cuda with an EZ wire 12 circuit kit. I have a buss block that I installed, powered from the ignition switch. (the ignition switch is powered by a 12 GA wire) and a 14 GA wire goes from the IGN switch power to power the buss block. I have a few terminals each of constant power, and key on power that go out from the buss block for the radio, cigarette lighter, and a couple other things, which are all 14 GA wire.

Should the 14 GA wire not be adequate for the Cig Lighter, I will have to change to 12 GA wire to power the buss block and run 12 GA from buss block to Cig lighter.

So my question is a 14 gauge wire adequate to power the cigarette lighter? or should I jump to a 12 gauge wire?
