I have a bought 2007 ECU + key and full kit thinking I can replace them with this car. but I have this power issue now. my kit I bought includes Year of donor vehicle: 2007 (2003-2009) Included: Engine ECU: 89661-47110 Clocks: 83800-47220 Network gateway: 89111-47020 ECU Immobiliser: 89780-47020 Door receiver: 89741-47100 Theft warning box: 89730-47020 Ignition barrel: 626399-000 BCM Fuse box: 41018-0368 1x OSF door lock 1x Key + Fob what should be my next step forward ?????
