Main beam flash (level Up) RPO TT6

When the dipped beam headlamps are on and the direction indicator/multifunction stalk is temporarily moved to the main beam flash position, ground is fed to the direction indicator/multifunction stalk. The direction indicator/multifunction stalk grounds BCM through the main beam flash signal circuit. BCM then grounds the main beam relay control circuit. This supplies current to the coil in the main beam relay so that the relay switch closes. It then feeds B+ to both of the dipped beam headlamps through the fuses for the left and right main beam so that the main beam headlamps come on.
