A-Premium Rear Parking Assist Sensors for Ford Lincoln Mercury — Pack of 4, OEM-fit 3-pin male connectors

The A-Premium Rear Parking Assist Sensor is a four-piece replacement kit designed to restore or upgrade the rear bumper proximity sensors on compatible Ford, Lincoln and Mercury vehicles.

This four-sensor set from A-Premium matches factory fit and connector type so you can replace damaged or missing rear parking sensors without rewiring. Each sensor features a three-pin male terminal and plugs into original vehicle harnesses listed in the fitment table, making installation straightforward for most do-it-yourselfers or professional installers. The sensors are sold as a pack of four to cover full rear bumper needs and are backed by A-Premium's one-year unlimited-mileage guarantee.

Which Ford, Lincoln and Mercury models will these sensors fit?

These parking assist sensors are designed for a broad range of models across Ford, Lincoln and Mercury lineups spanning late 1990s through mid-2010s model years. Fitment covers full-size trucks, vans, SUVs and select compact models where the OEM part numbers match those listed in the product reference section.

• Ford: F-150 (2004–2008); F-250/F-350/F-450/F-550 Super Duty (2001–2015 to 11/07/14); E-Series vans (2007–2019); Escape, Expedition, Explorer and others as specified.
• Lincoln: Blackwood, Mark LT, Navigator in early 2000s model years as listed.
• Mercury: Mariner and Mountaineer on compatible years noted in the detailed fitment.

How do these sensors match original equipment (OEM) specifications?

The A-Premium sensors are engineered to plug directly into the factory wiring and match OEM reference numbers, connector gender and terminal counts. That ensures electrical compatibility and simplified installation without modifying vehicle harnesses or control modules.

• Connector gender: male; terminal gender: male with three pins per sensor.
• Reference numbers include common OEM IDs (e.g., 4F23-15K859-AA, XF2Z-15K859-AA, 684-029) for cross-checking.
• Package contains four sensors to replace an entire rear bumper set at once.

What should I expect during installation and maintenance?

Installation is typically plug-and-play for vehicles that originally used these part numbers. You’ll remove the old sensors from the bumper, unplug the factory connector, and insert the new sensor until it clicks into place; always verify alignment and perform a system check afterward. Routine care is minimal—keep sensors free of heavy mud, ice, or debris for reliable detection.

• Simple unplug-and-plug replacement on compatible harnesses; no special tools usually required.
• Verify three-pin connection seating and secure sensor into bumper opening.
• Clean sensor faces periodically and clear obstructions for best performance.

Does the kit come with a warranty and what does it cover?

A-Premium includes a one-year unlimited-mileage guarantee that covers manufacturing defects under normal use. The warranty is intended to provide assurance for buyers replacing worn, damaged or nonfunctional sensors, but it does not cover damage from improper installation, collision damage, or misuse.

• One-year unlimited-mileage guarantee from A-Premium for manufacturing defects.
• Coverage applies to normal vehicle use; consult A-Premium for claim procedures.
• Not a substitute for professional diagnosis if vehicle electronics show other faults.

Who is this for: This four-pack is aimed at vehicle owners, mechanics and body shops that need a reliable, OEM-compatible replacement for rear parking sensors on select Ford, Lincoln and Mercury models. It’s especially useful when multiple sensors are damaged, when restoring a vehicle for resale, or when you prefer a full-set replacement to ensure evenly matched sensor performance across the rear bumper.
