My very crude diagram how to wire the diode for the high beam shutter and high beam bulb to work

The diode prevents the low beam from backfeeding and activating the shutter and high bulb. But the High Beam switch will activate the projector, shutter, and bulb.

I used a 15SQ045 Diode, found a pack of 20 on Amazon for $6.
