Just a suggestion,...why don't you leave the 12V cig lighter recepticles & just add the Anderson Power Pole plugs to the same box.
Then you will be able to power up just about any 12V accessory that comes along.
If you are having a problem with the length of the cig recepticles, You might look at these:

There are also several others available,...I found some (short) surface mount recepticles at a swap meet a while back that are water resistant & have mounted a couple on my motorcycle for the GPS & heated vest etc,...
