Help identify these wires!

I'm in need of some assistance. I purchased an 08 wr250X that had been stolen and stripped. I'm pretty close to finishing up but I dont know what these last wires went to on the bike. Also, my gauge lights up but the screen is blank. I'm hoping one of the cut wires will fix the gauge.

I think black/yellow and blue/yellow are the clutch switch on the handlebars. Not sure about gray/yellow.


I don't know what these are. Normally black with no other color is earth ground (0 volts), but It's not obvious if these are from the factory harness.


Pink and brown look like the horn wires to me.


This wiring diagram might be helpful.

Would the clutch switch affect the instrument gauge? If not, does anyone know someone who could repair a gauge that lights up but does not show any readings? The screen just lights up blue.
Thanks!
