    Hello

    Back again. Got a sprinter now. 2007 with startship mileage.

    Anyway. Today involved adding a reverse camera and tow bar.

    Fitted camera first. Tested fine. All done and dusted.

    Fitted towbar, really easy, except the wiring. I paid extra for a kit specific to the sprinter.

    Connected the can bus module to the X3 connector, pin 11 as described in the manual.

    Now I have no rear lights whatsoever. Brake, tail, fog, indicator hazard and reverse.

    All other lights work, including side markers.

    Checked every fuse under the left end of the dash and the three or four under the driver's seat. None blown.


    Any suggestions?

    Thanks

    Guy

    Hi,
    Adding a dedicated wiring harness for the towing electrics normally ( for cars ) needs to be coded in on a Star Diagnostic, have you checked whether this is necessary on a van.

    turns out the wiring harness tapped into the brake wire in connector X3, pin 11. this cheesed off the SAM as I think the brake and tail lights are one wire. so the sam shut down everything.

    remove this - let the system reboot. harness has a canbus interface which deals with the brake light.

    all working again.
