Replace factory Amp

I want to replace my OEM sub amp with an aftermarket on my 02 Navigator with an Alpine system. I bought a LOC but can't figure out the wiring. Where can I find the wiring diagram.

I found several diagrams, but nothing indicating a factory sub. I would say the easiest thing to do at this point is tap into the wires for the rear speakers for the LOC.

Thanks, for the reply. Figured out that you have to tap the harness behind the OEM Deck and attach the LOC there. That is the only way to use a aftermarket amp and then rip out the ford garbage amp and sub and rplace. Thanks for your help.
