Hi, im currently fitting a key less system and push button start but I have hit a problem. The push button works fine but I cant seem to wire up the power locks, I have searched about on google but cannot find a definitive answer as to which wires I should connect to, some say red and light blue at drivers door module, others say white and pink at bcm, I have tested all of these with a multimeter and none of them are showing as a negative trigger. Could I possibly have to go direct to actuator in drivers door? any input would be greatly appreciated. Thanks Jon
