Reconnect the turbocharger boost control solenoid to the engine wiring harness with the Standard Ignition Turbocharger Boost Solenoid Connector S2491. It installs as a direct-fit replacement for the listed applications: the 2013-2016 Ford Escape, 2014-2019 Ford Fiesta, 2013-2014 Ford Fusion, and 2014-2016 Ford Transit Connect.
- What it does: Provides the electrical connection between the vehicle's wiring harness and the turbocharger boost (wastegate/vacuum) solenoid so the circuit can carry signal and power.
- Why replace it: Connectors and their terminals can corrode, melt, loosen, or crack over time; if a damaged connector is the cause of an intermittent or open connection at the solenoid, this replaces it.
- Direct-fit: Installs as a direct-fit replacement for the listed applications.
A worn or broken connector can show up as a poor or intermittent connection at the boost solenoid. Diagnose the underlying cause before replacing, since the same symptom can come from the solenoid, wiring, or elsewhere in the circuit.
Interchange: Manufacturer part number S2491.

Which vehicles does it fit?
It is a direct-fit replacement for the 2013-2016 Ford Escape, 2014-2019 Ford Fiesta, 2013-2014 Ford Fusion, and 2014-2016 Ford Transit Connect. See the Buyer's Guide tab to confirm your vehicle.
What does this connector do?
It provides the electrical connection between the wiring harness and the turbocharger boost solenoid so the circuit can carry the signal and power to that solenoid.
When should I replace the connector?
Consider it when the original connector is corroded, melted, loose, or cracked. If a damaged connector is causing a poor or intermittent connection at the solenoid, this replaces it.
