🔌 Genuine GM OEM Front Parking Aid Sensor Wiring Harness with Sensors — 2019-2023 GMC Sierra / Chevrolet Silverado HD | Part# 84540583 with 84360392 Sensors

Used OEM front bumper parking aid sensor wiring harness removed from a 2019-2023 GMC Sierra or Chevrolet Silverado HD. Complete assembly — harness with all ultrasonic parking sensors still attached and intact. Genuine GM parts throughout. The harness includes the main 12-pin bumper-to-vehicle connector, multiple sensor pigtail connectors (yellow 2-pin, black multi-pin), and GM 84360392 ultrasonic parking sensors. This is a direct plug-and-play replacement for vehicles displaying "Service Park Assist" — the complete assembly eliminates the need to diagnose individual sensors.
