help with the electronics/wiring[Helped]

[cmat1120]

So I have been looking at the wiring and its schematic for a bit and I can't figure something out. I need to find a 12v line that will be active when the kill switch is on and inactive when it is off. Can someone help me figure out where to tap in? also preferably a clean line(no crazy voltage spikes running across it), but it shouldn't really matter much if I don't have a choice.

Thank you!

You fitting an alarm? .... If so .... the tail light wire ... Not the brake! ... The other wire! ... Assuming you have 'always on lights/no headlight switch on right bar cluster'

If you truly want a circuit that is controlled by the "Engine stop switch", it looks to me like you need to tap into one of the Orange/white wires.  (Some of the possible locations are indicated by blue arrows in the diagram below.  The wire on the lower right leads to the "Ignition control unit", otherwise known as the black box.)

Not exactly, I'm actually replacing/adding a different from of turning the bike on (keyless). So I need a wire that will have power(if grounded) when the kill switch is on, but will not when it is off. It's sort of hard to explain, so hopefully someone who understands electronics well can understand what I'm trying to say. One way to think of it is I need a wire that I can use to turn "idk a 12v lightbulb" on/off using the kill switch without inhibiting the kill switch's normal functions. Hopefully that makes sense.

Also mine is a 1990 and I don't think it has that switch, but I may be wrong. ( I lost the keys so I cant check what the worn switches do right now)

Edit: In response to Kerry: That's what I was maybe thinking, but I wasn't sure since it goes so many places it seemed like it may get cut off somewhere else. I'll check it though with a multimeter and post my findings.

Hmmm....  Well, the Orange/white wires won't have power at all unless the keyed Ignition switch is also turned ON.

Does that change things?

Ya thank you Kerry, that does change it. What im trying to do needs to work without the key. But I just realized that I was over complicating things and I can just attach my electronics to the battery and just add an extra on/off switch directly to the electronics. I would've been nice to integrate it. but this is probably better anyways. Thank you for your help. Hopefully I'll be able to post this as a finished project soon.
