Hi. I have a 2018 AWD Toyota Highlander with a 4-pin connector. I'm going to be towing a popup with a 7-pin connector so I'll need an adapter. What I'm wondering is if it's reasonable to simply use the adapter without connecting the wires for brakes, aux power, and reverse lights. The trailer is 15.5 feet with a dry weight of ~1875lbs and GVWR of 2750lbs. I was considering getting a sway bar and a 4 to 7 pin adapter and simply not connecting the additional wires (saving myself some work and purchasing a brake controller). Does this sound like a reasonable approach? Thanks.
