Why You Need This

When building a custom engine loom or replacing damaged ECU connectors, using the correct AMP connector is absolutely critical. Cheap aftermarket alternatives or incorrect key configurations will either fail to mate properly or create intermittent connections that can destroy expensive ECUs. This genuine AMP connector uses the precise Key 1 configuration required by Haltech's ECU range, ensuring proper pin alignment and secure locking.

We see this connector specified across diverse builds - from LS swap projects in BMW E36s where the original loom is incompatible, to rotary builds requiring custom sensor integration, and classic car EFI conversions where no OEM connector exists. The 26-pin configuration handles the primary engine control signals including injectors, ignition outputs, sensor inputs, and auxiliary functions. Professional installers know that connector reliability directly impacts tune stability - a loose connection on an injector circuit or sensor input will manifest as seemingly random running issues that waste hours on the dyno.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus ECU range including Elite 550, 750, 1000, 1500, 2000, and 2500 models, plus all Nexus R3 and R5 variants. The Key 1 configuration is standard across these platforms, ensuring universal fitment.
