Our 2021 Tucson Ultimate manual mentions parking sensors but they are not present on the vehicle. (parking sensors are those proximity sensors that warn you by beeping when you are about to back into something) My assumption is that in some locations (like Canada or UK), these sensors are included with the vehicle. So, I was thinking about installing an aftermarket version of these sensors. However, looking under the rear bumper, I noticed a wiring bundle running the length of the rear bumper. I wonder if the Tucson is already wired for the sensors, buy they were not included in the US version. Does anybody have a wiring diagram that shows what these wires are? The aftermarket sensors just need a reverse light power wire to operate. A second wire runs from the sensor to a "beeper" - if the wiring is already there, the beeper wire may be there also.

Thanks to all that reply.
