jochen 4 Report post Posted June 11, 2006 Hi, If you only have one wire to activate the indicator lights, then you need to use a diode to connect the two indicator circuits together The indicator wires are Blue/Red (L) and Blue/Black ® - you can find these wires either at the instrument cluser or on the hazard light switch, which ever is most convenient to you. Connect the diodes like this: --------------->|----------to indicator (left) from alarm -----+ --------------->|----------to indicator (right) Your diodes must be able to handle the total current of all indicator lightbulbs, including any trailer lights (if you have a towbar of plan to add one) So budget for 2 x 21W (front + rear) + 5W (side) + 5W (dash) + 21W (trailer) = 73W which is @12 V = 6 amps So buy 2 x 6Amp (or higher) diodes and you'll be right For the central locking you'll have to look at the wiring diagram for the central locking for your car Jochen Quote Share this post Link to post Share on other sites
