Audio wiring questions for 08 grand cherokee

Hello, I have an 08 grand cherokee and am in the process of installing a pioneer head unit. I am having issues with wiring. First, why are there two plugs going into the factory unit? What is each one used for? I'm trying to match everything up for the pioneer harness, however, of all of the wiring charts I've seen online, none of them match my color codes. Also, any knowledge of what to connect the red wire to? When I don't wire to anything, no juice to the unit, but when I wire together with my yellow I get juice, however it stays on when the car is off. I have no red in the jeep wiring, so no clue where it goes. Also, I've been reading conflicting info regarding the colors of the wiring for the rear/front speakers. Any help would be appreciated!

Thanks for the info...however, I cut out the one harness from the jeep. The bigger of the two. The other one is still in-tact, however I made the mistake of cutting this one....any help with that?

Use some of these to reconnect the harness...[they're called butt end splices]

Yes, you really shouldn't be cutting anything. If you bought the right harnesses the factory wiring doesn't need to be altered.
