There is this download of the whole set of factory manuals, electrical, shop, overhaul, owner's, etc. - called the RAVE. Free below. Here's pages from the electrical, including the stock sub amp wiring (has power) and AC wiring (if you don't have rear AC may have the harness for it). And after I checked the RAVE, it is yellow/green for the rear AC power. On the existing subs the power is on light-green/orange.
