The trailer connector plugs have been on the right side of the license plate since 2013.My 2019 3500 SRW had the plug cover on the left side of the license plate (4 Pin flat over the 7 Pin round).
I think the confusion started when @mbarber84 was asking @Steelman2500 about the presence of the tow mode connector on his truck, but @CajunMan. replied thinking he was being asked about his truck.
Either way, the connector configuration on both their trucks are odd/don’t make sense.
Below is @Steelman2500 truck. He has the connector for the tow mode camera and the 12-pin trailer connector, but does not have the tow mode camera option that gives you that connector, or the trailer surround view or mopar trailer camera option that would give you the 12-pin connector-
Below is @CajunMan. truck. He does not have the tow mode camera option, and has the tow mode camera blank that you would expect. He also does not have the trailer surround view or mopar trailer camera option that use the 12-pin, but has the 12-pin connector present-
There just doesn’t seam to be any reason why some of these trucks have the connectors when they’re not supposed to, and some don’t have those connectors when they are not supposed to.
