I got my Armada with the tow package -- so not clear on this ...but just before I got my ARmada...I had just finished doing the same thing to my Jeep Grand Cherokee -- and I would recommend the OEM hitch...not a cheap Uhaul hitch. It would have been night and day -- and I stress tested that OEM hitch with a 6500lb boat on an 18hr round trip to Nag's Head...and it held up just fine...but the Jeep was dying a slow death -- hence the Armada. I guess it depends on what you're planning on towing...
Regarding the electronics...that's another reason to get the OEM equipment...it will come with good instructions...but if I get a second tonight...I'll look in the service manual to see what I can find.
