Before you contact us
Send the details that let us give a useful answer
For the fastest reply, include the engine family, exact engine code, ECU part number, transmission type, throttle type, donor vehicle, swap vehicle, and clear photos of the harness, ECU labels, plugs, and engine bay.
- Do not send parts until the correct client form is completed.
- Tell us whether you need a new harness, a rebuilt harness, ECU-only work, or wiring advice before ordering parts.
- If the project uses GR or UR electronics, include as much donor-package information as possible because ECU, immobilizer, CAN, and transmission requirements vary widely.
