Well looks like one of my rear parking sensors took a crap. It was working fine all day, then after work I got the solid tone after engaging reverse. Seems to be my left inner sensor is bad.

My question is, has anyone replaced one? Also if so, is it a PIA to do or simple since I've never taken off my rear bumper.

Hi, I need to know if the rear sensors are equal to the front sensors, because I have 4 rear sensors new and I need to use them on front bumper. Somebody knows how to wire this, because I have not the harness of the front bumper, but I have the rear harness . And it have 12 wires compared with the front harness that is only 6 wires. Thanks
