Has anyone installed BOTH the MOPAR flat tow (tow vehicle) wiring harness - 82215382AB - as well as the tow hitch wiring harness - 82215896 - on a JL? Any issues I need to be aware of? Does it matter which sequence the harnesses are connected to the existing brake light harness? Parts coming next week and hoping to get it done on a Saturday morning. Have watched a bunch of videos on each individual install, but nothing that shows both harnesses installed at the same time. Thanks!
