I have an 08 XLT...was wondering if the wiring hook up thats suppose to be underneath the drivers side back seat should be there for the factory systems? I was going to purchase one if all I had to do was plug and play.

 

Don't count on it. My 2008 Lariat didn't have a plug back there. If you don't have a plug, aftermarket is better anyway. You would also need an audiophile head unit to use the factory subwoofer too. The audiophile systems have three plugs in the back, whereas yours only has two.
