Not confident with automotive wiring? Have a professional harness builder or tuner do it, or check your work before first power-up. A wiring mistake can damage the ECU, the engine or the car, or start a fire.
Repin guide
Move each wire from its OEM cavity to the new ECU cavity. The terminal family and extraction tool are shown per side; buy a socket terminal for the ECU side when its family differs from the OEM side.
Some cavities have no terminal family recorded yet, so tools and terminals are incomplete.
