I made a 7 pin trailer plug with resistors that fools the truck into thinking that there is a trailer hooked up so that my turn signal camera works whenever I use the signals. When I first got the truck I was playing around in the settings and saw an option that would allow the rear sensors to be active with a trailer connected. I want to use that option now but I can’t seem to find it again. Can someone tell me how to access it. 2024 GMC Sierra SLE
