Why You Need This

High-performance builds demand bulletproof electrical connections, especially when you're pushing serious power through fuel pumps, cooling fans, or auxiliary systems. Standard automotive connectors simply aren't designed for the sustained high-current loads found in race applications — they overheat, create voltage drops, and ultimately fail when you need them most. We've seen too many promising dyno sessions or race weekends ruined by a £5 connector that couldn't handle the current.

The SurLok design eliminates these failure points with a precision-machined aluminium body that dissipates heat effectively while maintaining perfect electrical contact. Whether you're running twin Bosch 044 pumps on an E85-fed 2JZ build, powering high-draw cooling fans on a circuit car, or switching nitrous solenoids on a drag setup, this connector handles the current without the voltage drop that kills performance. The black finish isn't just aesthetics — it's part of the thermal management strategy that keeps connections cool under load.

ECU & System Compatibility

Specifically engineered for Haltech Nexus R3 ECU systems. The connector integrates seamlessly with the Nexus R3's advanced I/O capabilities, allowing you to switch high-current loads directly through the ECU's outputs without compromising system reliability.
