MecXora MAP Sensor & Wiring Harness for GM Vehicles - 3-Pin Connector, 16-Gauge Prewired Kit

This replacement MAP (Manifold Absolute Pressure) sensor and matching connector wiring harness are built to match a long list of legacy GM and compatible applications, including Chevy Impala, Malibu, S10, Blazer, K1500, GMC Jimmy, Buick Century, Oldsmobile Alero and Isuzu Rodeo models. The package includes the sensor, a molded connector harness with male terminals, and three spare terminals. Before installation, cross-check the listed part numbers and connector style with your factory component to ensure correct fit.

How do I know this sensor fits my vehicle?

Fitment is determined by part number and connector type rather than vehicle make alone. MecXora lists multiple OEM cross-references included with this unit; matching one of those numbers to your original part is the fastest way to confirm compatibility.

• Compare your existing sensor’s part number (e.g., 12569240, 88862232) to the provided cross-reference list.
• Verify the sensor’s 3-pin female bullet connector matches your vehicle harness shape.
• Check model years and vehicle lists for common GM and Isuzu applications in the 1980s–early 2000s.

What does the harness and connector include, and how is it assembled?

The kit ships with a pre-wired connector harness built from 16-gauge wire and three male terminals to mate with the sensor’s female bullet plugs. Terminals are included for crimp or replace-and-seat repairs, allowing either direct plug-in replacement or simple splice work during installation.

• One MAP sensor with 3-pin female bullet connector for a secure plug-in interface.
• One connector wiring harness pre-crimped with 16-gauge male terminals for durability.
• Three spare terminals for replacement or wiring adjustments during install.

How durable is this replacement compared with the factory unit?

MecXora manufactures this sensor and harness to a regular-grade durability standard suitable for common driving conditions. The materials used—molded connector, 16-gauge wiring, and metal terminals—are intended for reliable electrical contact and resistance to everyday vibration and heat.

• Molded body and secure 3-pin female bullet connector to limit moisture intrusion.
• 16-gauge wires for consistent signal transmission and mechanical strength.
• Backed by a 1-year warranty and customer support for fitment or installation questions.

Can I install this myself, and what tools do I need?

Basic mechanical and electrical skills are usually sufficient for installation. Typical installs require disconnecting the battery, unplugging the old sensor, transferring or crimping terminals, and securing the new harness in the same routing path.

• Tools: basic hand tools, wire crimper, small pick or terminal release tool, and dielectric grease for connections.
• Optional: multimeter to verify signal and continuity after installation.
• Follow OEM service manual torque and safety steps when working near the intake manifold.

Who is this for: This MecXora MAP sensor and connector wiring harness is aimed at DIY mechanics, professional technicians, and owners of older GM and compatible vehicles needing a reliable replacement for a worn or faulty MAP sensor. It suits anyone who prefers a direct-fit, cross-referenced part number match and a harness ready for straightforward installation, with spare terminals included to simplify wiring repairs.
