The used OEM Mercedes-Benz front bumper/park assist wiring harness (1665408632) connects the parking sensors and bumper lighting on GL450 and GLS63 AMG models with the 4.7L or 5.5L turbocharged V8. Also called the bumper wiring harness or park assist harness, it carries power and signal to the front sensors. A failing harness can trigger intermittent sensor faults or complete loss of park assist function. This original Mercedes part restores reliable sensor communication.
