Fuel Injector Connector for BMW Applications

Standard Ignition S3112 is a fuel injector connector built for BMW air and fuel delivery repairs where the injector plug or pigtail has failed. It uses a rectangular male connector housing with female blade terminals and a 2-wire layout for a direct electrical connection at the injector.

With a 17-inch harness length and 18-gauge wire, this connector is suited for repairing damaged injector wiring on BMW 135i, 335i, 535i, 550i, 650i, 740i, M5, M6, X1, X3, X5, and X6 models. Standard Ignition S3112 is also cross-referenced to 7507527 and EC3139 for the same application.

Key Features

  • Fuel injector connector for air and fuel delivery electrical repair
  • Standard Ignition S3112 part number for catalog lookup and replacement matching
  • Male rectangular connector housing with female blade terminals

Detailed Product Overview

This connector is used to restore the electrical connection at the fuel injector when the original plug is heat-damaged, broken, corroded, or no longer locks securely. The rectangular housing and blade-style terminals support a stable injector connection, while the 430 mm harness length provides added reach for repair work in the engine bay. Standard Ignition S3112 is a practical replacement choice for BMW fuel injector connector service across 2011-2019 model coverage, including 2014-2019 BMW 650i Gran Coupe, 2012-2018 BMW M6, 2013-2018 BMW 650i, and 2011-2014 BMW 535i.

Installation Notes and Tips

Verify connector shape, terminal style, and harness length against the original injector lead before installation.

Confirm proper terminal seating and secure locking engagement after installation to maintain a reliable electrical connection.
