I want to install electric windows into my EL FUTURA rear doors along with the courtesy lights, and I want to make it AS FACTORY AS POSSIBLE.

Are the rear windows powered by ADDITIONAL looms that connect to the main interior loom of the Futura and Fairmont models? If this is the case, I can get those additional looms and plug it into my current loom in my Futura that already has electric windows in the front?

ANY INFORMATION HELPFUL!

(I know there is a resource forum on adding electric windows, but it contains no information on factory wiring.)
