So the front end components will bolt right up to the existing locations with the hold up being the lights - I know there was a guy making a harness adapter for just such an occasion
I kno he ended up buying 14 lights that fit the 2012. Same exact headlight. I bought them from him. I will be installing them soon. They are really nice
And I seriously want to know what the point is for the inner headlights on a 12-13. They don't seem to do anything other than illuminate a orange glow..
I'm not sure where he got them but u can Google it and I remember something of the same sort popped up. My car is undergoing a big builds right now so it will be a minute but I will post pics. I buffed out these ones and there good as new. The quality is very nive. I'll see if I can get it touch with him
He got them off eBay if I recall correctly. They were technically for the other Jeep SUV, but they fit the Grand Cherokee perfectly with some custom wiring.
