Rover 45 bumper help?

DONT KNOW ABOUT THE ROVER BUT USUALLY CAR MANUFACTURES BUILD THEM EASY TO INSTALL AT THE FACTORY, I WOULD BET THERE IS ONE OR TWO WIRING HARNESS POINTS THAT UNPLUG SO YOU CAN REMOVE THE WHOLE THING PUT IT ON THE BENCH TAKE OUT THE SENSORS REINSTALL IN THE NEW ONE AND THEN BOLT BACK ON THE CAR AND THEN PLUG INTO THE MAIN HARNESS, THAT HOW ALL AMERICAN CARS ARE, PEOPLE JUST DONT TAKE THE TIME TO LAY DOWN UNDER THERE AND LOOK, A LOT IF TIMES THEY ARE COVERED IN TAPE WRAPPED SO LOOK CLOSELY, IF THEY ARE PUT THEM BACK THAT WAY TO KEEP OUT WATER
