All 2st What is this?

I'm trying to hook up my lights. There is one yellow wire comming from the stator that plugs into the regulator. Now the light harness has two yellow wires one with the male flat blade and the other with the female flat blade. It seems like I have to many yellow wires. The wiring diagram not in english, and doesn't show this extra part. And what is this part for?

on mine, 06 wr125, i have a blue and a yellow mini spade connector. they are both female though an they never stay plugged in for more then a minute of riding.

It's a resistor for the lights

How is this used with the current harness? Does anyone have a wiring diagram?

I think it's a diode if you are using a battery. I didn't use it on my WR300 and my lights work fine.

I pulgged it in and it got hot but the lights worked. I thought that without it I could blow out the headlight bulb. I seen where my buddy did that on his xc200. I'll try without it.

I think it is so the odometer can work without a battery. I was told the odometer/computer will not last without it.

I'm not going to run the speedo so that works for me.

a wiring diagram would have been damn helpful

Wiring harness

They gave me one...not in English of course. And it does not show this part in the diagram. I should be happy at least the bike comes with a headlight.
