Hi, I'm in the middle of adding "remote" function to the central locking in 2012 Berlingo Van. I've sussed out where to wire to for to get the locks opening and closing but I'm wondering if anyone knows how to get the indicators to flash. There's a wire to send signal from the remote locking control unit but I don't know where to send it to. Hazard light switch is no use as that just requires a signal to a wire to turn hazards on and a signal to the same wire to turn them off. I'm looking for where to send the siganl so that that they flash at the tempo set by the remote locking unit. Any help appreciated. Ask any questions. Thanks
