I am not sure if this has been asked and if has I am sorry. I would like to install some aux lights. Two on the windshield and two on the bumper. Then later on add some above the windshield after I build a rack. Ok my question are.

-I would like to put JK Lower Dash Switch Panel with 4 switches. But only two will be used. Then I saw the 12 volt power adapter which connects to the ignition lead or something like that. Do I have to install this??
-If I do have to install this how many switches can I run on it?
-If I only can run one switch can I install more than one 12 volt adapter?

Sorry for all the question I am rookie and all excited about adding to my first JK.
-If there is a better set up please let me know.
