I ordered a KTM Euro switch
(P/N: 60011074000) to put on my SE. I want to have the ability to turn the headlight off. I also plan to wire in my aux. lights as shown here by dad2bike
to eliminate another thing on the handlebar.
I assumed this was gonna be plug & play. Turns out the molex connection that controls the existing right hand switch is a flat 4 pin. The new euro switch I have is a 9 pin molex connection w/ 7 pins existing... not exactly plug & play.
