As I mentioned, the turn lights (Stop/turn light too) will require a resistor to prevent hyper flash. All other lighting, interior and exterior, will be plug & play. Some guys have issues with interior lights remaining dimly lit at all times, not sure why that happens, (maybe cheap Ebay lights). I replaced all my lighting with LEDs, other than headlights and foglights, and have no issues whatsoever. I order from Superbrightleds.com for both my car and truck.
