used srx
 

hello everyone,
we just bought a 2014 srx, i guess it's the base unit, not to many bells and whistles, anyway, just because it doesn't have certain things, does that mean you can't install them? are they wired with the correct harness to put in others items? like the passenger seat is not power, is it wired for it anyway? if i got a power seat, would i be able to make it work? are the connections already there? even with the lighted sill plates, can they be installed, and hooked up to the harness? also, where is a good place to buy oem parts reasonable? any help would be greatly appreciated. thank you
