Hey guys I'm a newb to Explorers and I have a question about the back up alarm on my 2017 XLT. To date, I haven't towed anything but on July 4th I mounted a flag pole and naturally, when in reverse, the alarm went off because it was just a foot or so from my bumper. I wondered if I had a trailer with a harness hooked up that would turn off the alarm because I imagine backing up a trailer with that alarm sounding would be very annoying. Now, IF having a harness connected does turn the alarm off, is there a dummy plug of some sort I could connect just to override the reverse alarm for when I have my flag pole holder or cargo carrier on? Thanks for your input!
