I want to install a back up camera kit in my 05 WK. I already have the Mygig RER installed with lockpick, etc. and all is working fine. My question in the liftgate lightbar. Can I use the stock lift handle and cut a hole for the factory kit or do I have to get a liftbar that has the hole in it from the factory? Also, do I need to go to a dealership to activate the camera function once installed or will the Mygig work ok after connecting everything?
