The U-connect system is a wiring harness that enables the complete Unichip installation without cutting or tampering with the original wiring harness of the vehicle. You simply unplug the ECU wiring and install this system between the male and female plugs. All the necessary original male and female plugs are included in the harness. In this way you can add or remove the complete Unichip system whenever you want. Once removed there will be no footprint or trace of the original installation at all. The U-connect is available for most electronically controlled diesel vehicles and some petrol versions. Check with your local dealer if available for your specific vehicle.
