Has anyone installed an interior mounted brake controller inside their 2021 telluride. Ours did not come with towing package from the factory but the dealer did the hitch and harness as an accessory... it has the 7-pin connector. The brake controller companies don't seem to have anything in their databases yet and I haven't heard back from Tekonsha. I'd expect that they'd sell a 2 connector adapter cable and have details on mounting... but nothing yet. We have a popup trailer with electronic brakes and so the 7-pin wiring is a must.
