Detailed Description

Standard Ignition S-2104 is an electrical connector assembly used for manifold absolute pressure sensor service and related sensor wiring repairs. The female terminal design, 3-wire configuration, and blade-style contacts support a secure connection where the original plug has cracked, loosened, or suffered terminal wear. Its 1.5-inch connector body and 311.15 mm harness length provide a compact repair solution for underhood electrical work.

This connector cross-references PT2091 and EC2005 for the same application. It is listed across a broad range of vehicles, including 1999-2003 Nissan Frontier, 2000-2003 Nissan Xterra, 1995-1999 Nissan Maxima, and 1997-2001 INFINITI Q45. The S-2104 also appears in fitment for several Ford and Mercury models where multiple connectors may be required for certain repairs.

Common Repair Uses

• Broken or cracked MAP sensor connector housing
• Loose or corroded sensor terminal connection
• Damaged wiring near the engine harness
• Intermittent sensor signal caused by worn connector contacts
• Restoration of factory-style electrical connection on Nissan and INFINITI engine management systems

Installation Notes and Tips

Verify connector shape, terminal count, and wire configuration before installation. Match the oval 3-terminal layout to the original connector on the vehicle, and inspect the harness routing for heat damage or abrasion before splicing. Because this connector is not weather resistant or weatherproof sealed, proper routing and secure mounting are important in exposed engine-bay locations.

Fitment examples include Fits 1999-2003 Nissan Frontier, N/A; Fits 2000-2003 Nissan Xterra, N/A; Fits 1995-1999 Nissan Maxima, N/A; and Fits 1997-2001 INFINITI Q45, N/A. Additional coverage includes Nissan Pathfinder, 240SX, 300ZX, Sentra, and select Ford Bronco, F-150, Mustang, and Ranger applications.

Quality Assurance

Standard Ignition supplies replacement electrical components for automotive repair applications, and S-2104 is built to match the connector style and terminal layout used in listed vehicle applications. Confirm the original connector design and sensor location before ordering to ensure proper application matching.
