Heavy Equipment Electronics, Verified to Fit
Aftermarket and remanufactured ECM controllers, generator panels, displays and harnesses — bench-tested by our own technicians before anything ships.
Not sure it fits? Ask before you order.
Part numbers supersede, and control modules vary by machine arrangement rather than engine model alone. Send us your engine serial number, machine model or the number on the failed unit — we confirm the correct replacement before you spend anything.
We diagnose and repair at board level with our own microscope bench and technicians. Every electronic unit is powered up and function-tested before packing.
Control modules are configured to the ESN or VIN you supply before dispatch, so the unit is ready to fit on arrival. No emissions systems are modified.
Dispatch in 1–3 business days. Express via DHL, FedEx or UPS in 3–8 days, tracking issued within 24–48 hours.

Fields marked * are required. Including your ESN or VIN speeds things up considerably.

We specialise in high-value, mission-critical components — engine control modules, generator control panels, operator displays, wiring harnesses, sensors and fuel system parts.
