Wiring noob needs advice

I enjoy working on my XR650R but don't get the electrical stuff. So I'm looking at my rear brake light wires - because I'm going to connect a Baja Designs front brake switch - Brown and white wires go in to their connectors but a third green/white wire with connector is not plugged into anything. Is this a ground? I don't see where it goes. Anyway, how can I really get this electrical stuff down? The shop manual doesn't have much detail other than a general schematic. Do I have to get an electrical engineering degree to be able to wire one of these bikes? Sheeesh!

Dunno..On the older 600's etc a Green/Yellow would be for the foot brake switch.Probably what the G/White in your situation is for.I don't have a diagram for the 650 so can't be certain.It should be linked with another G/Y or in your case G/W which comes down from the front hand brake activation switch.

I don't know if this is right, but I remember reading somewhere that the 650R's have the capacity for a dual-filament bulb, meaning that you can wire a brake light to them.

Now, there is three wires, right? Usually one wire will be your ground, another will be one that is constantly 'on', and the third should be your braking signal that should go to your brake switch. This will make your bulb go really bright when you hit the brake pedal.

At least I think thats how it works...

The third Green\white wire..what part of the bike is it close too.

I have a baja designs kit on mine,it was a real POS to get the wiring sorted out.

I will have my tank off later today so will be able to see all the wires if you need more info.

      I just bought a 2012 xr650l and it starts and runs great until about 4000 rpm give or take (I’m guessing) it feels like it spits and pukes. Also when releasing the throttle the exhaust pops and hiccups. I am calling the dealership to ask if they are willing to fix the problem as I just purchased from them yesterday but I am curious as to what the problem could be in case they do not offer to help for my “as is” purchase. I have read a couple other topics on here that talk about the vacuum lines being hooked up to an air cut diaphram but I don’t know what that is. The smog delete has been done on this bike as well as a slip on dg exhaust and the side cover has a bunch of holes drilled in it exposing the air filter. The battery has also been relocated. My question is what jetting should I have at 2000 feet? I am planning on opening up the carb to see what the idle jet and main jet are and if they were even changed from stock. Also if someone knows about the air cut being hooked up to vacuum and can supply pictures that would be very helpful. I know that the smog block off kits just plug the vacuum holes and the air cut usually gets disconnected. Thanks.
