Should not be too difficult just have to follow instructions. If you are using a MOPAR brand check with the Dealer, they will install it. I'm not sure but if the Dealer installed it then it night be covered under your warranty. Please check that first to make sure.
I checked into installing one on mine. I ended up cheating and letting the dealer install it because of timing. It looked fairly simple in the directions that I read. The trick is getting the computer to understand that it's there. The benefit to the dealer doing it (roughly $350) is that now it's in the system with the vin and they have to deal with it, & it's covered under my warranty now also.
