I want to add a Mopar LED chmsl / cargo camera to my 2018 RAM 1500 Laramie. Is there more than one Mopar LED 3rd brake light w camera option to physically fit my truck ? I drive a 2018 RAM 1500 Laramie CC SB. So far I have found TWO part numbers (Mopar 68163937AA-AL and Mopar 68170934AI). The first one seems to be about 2X the price. Can you tell me the difference between these two ? The first one is listed for the HD's, though I think it should fit my truck mechanically. I realize that I will have to wire or buy a wiring harness to fit this to my truck, but electrical projects are "in my wheelhouse". Thanks for the help !
