TE Type Reversing Radar Waterproof Connector – 1-1718645-1 / 1-1670916-1, 2–6 Pin

TE Connectivity (formerly AMP) type waterproof connectors for automotive parking sensor (reversing radar) and rear camera systems. These connectors are used on the sensor-to-harness interface of ultrasonic parking sensors, electromagnetic parking sensors, and reversing camera power/signal connections. The OEM part numbers 1-1718645-1 and 1-1670916-1 are widely used across multiple vehicle platforms and aftermarket parking sensor kits, making these connectors the standard replacement for damaged sensor pigtails and harness ends.

Parking Sensor Connector Pin Assignments

Pin assignments vary by vehicle manufacturer and sensor type. Common configurations:

• 2-pin (simple sensors): Pin 1 = +12V supply, Pin 2 = Signal/GND return
• 3-pin (standard ultrasonic): Pin 1 = +12V, Pin 2 = Signal, Pin 3 = GND
• 4-pin (with shield): Pin 1 = +12V, Pin 2 = Signal+, Pin 3 = Signal-, Pin 4 = GND/Shield
• Note: Always verify pin assignment against the vehicle wiring diagram or sensor datasheet before connecting. Incorrect polarity damages the sensor electronics.

What Questions Does This Product Answer?

• "How do I identify a damaged parking sensor connector?" — Common failure signs: (1) intermittent sensor fault codes (sensor not detected by PDC module); (2) visible corrosion or green oxidation on connector pins; (3) cracked or broken connector housing from impact; (4) water ingress causing sensor malfunction after rain. Replace the connector pigtail rather than the entire sensor harness when only the connector end is damaged.
• "Are 1-1718645-1 and 1-1670916-1 the same connector?" — These are related TE Connectivity part numbers in the same connector family, differing in pin count and housing configuration. 1-1718645-1 is typically the female receptacle (sensor side); 1-1670916-1 is typically the male plug (harness side). Verify the specific pin count and gender required for your application.
• "Can I use these connectors for aftermarket parking sensor kits?" — Yes. Many aftermarket parking sensor kits use TE Connectivity compatible connectors. Match the pin count and gender to the sensor and control module connectors in your kit.
• "What causes parking sensor connector corrosion?" — Parking sensors are mounted in the bumper — a high-exposure location for road spray, car wash water, and winter road salt. Connector seal degradation (from UV exposure, thermal cycling, or physical damage) allows moisture ingress. Replace the connector and apply dielectric grease to the mated contacts to prevent recurrence.

Typical Applications

• OEM parking sensor repair: Replacing damaged sensor-to-harness connectors on BMW, Mercedes, Audi, Toyota, and other vehicles using TE Connectivity compatible connectors
• Aftermarket PDC installation: Connecting aftermarket parking sensor kits to vehicle harnesses
• Reversing camera wiring: Power and signal connections for aftermarket reversing cameras
• Sensor harness extension: Adding connector interfaces to extended sensor harnesses
