Where does the headlight get it's power from?

[Clerek]

I am trying to follow the wiring diagram and I am confused as to where the headlight get's it's power from. I took apart the LHS and there are four wires that are connected to the hi/lo beam switch:yellow, green, blue/green, and blue/yellow. I no longer have the RLU so I connected the blue/yellow wires and the blue/black wire. Also on the other side of the RLU plug I connected the blue/green and the yellow wires. On the schematic I was looking at http://home.comcast.net/~sidhansen/rlu/schematic.gif it shows that the blue black wire is what is the start of the circuit, and goes through depending on if it is on hi or lo. I am not using the middle console, speedometer or tach, and this is the only place I can see that would supply power, though it isn't clear. Can someone please clerify for me? I am trying to locate the main power for the headlight.

Thanks,

I may have figured out a way around it...can I use the red/yellow wire on the RHS? I read it on the UK site. I piggy back off the red/yellow wire (BTW what is the purpose of this wire in the RHS?) and connect it to the green low beam wire. The reason I ask the purpose of the red/yellow, is because on the RHS all that is really on there is the emergency kill and the start button. When you put the switch on start, does this wire supply power to the lights, and so on? So, will splicing off the red/yellow wire to the green wire (low beam) will that work? I still need help with the high beam too...

Sorry I guess it doesn't make sence if I just say a bunch of wire colors. Here is the wiring diagram I am trying to untangle:



Keep in mind that I am bypassing the Reserve Lighting Unit, and am also not using the middle console, speedometer, and tachometer.

It is powered from the altenator after starting the engine. Actually, I believe the powering of the altenator completes the circuit ast the headlight will remain on when the engine dies.

That is because of the RLU. There is a relay that switches once the engine turns over and gets power from the alternator, but after that, the power comes from the battery, via the headlight fuse.

Ah yes,
Where is Prom when you need him?
