Dude, with regards to your diagram, no luck. It didn't worked. I think it is because in your diagram you used an external connection. What I mean is because the connection of the switches is running and is activated in a close circuit then pass through the BCU then the magnetic switches will be activated. The loop of the circuit is complete. But if we insert or make a tapping of any wiring from outside (did not pass through the BCU) then the switches will not work because the loop is open. I hope you understand what I mean.
When I measured the amp that is being used to make the solenoid work in the projector reads .11amp. So I guess the BCU treats it as under-rated that is why it cuts the supply. Unlike if a halogen bulb is used the amp rating is high and continues to power the beam from hi/lo or vice versa. So because the solenoid only needs a very small amount of current for a short period of time which is .11amp the BCU treats it as an error in the lighting system.
Hope you understand me guys...
