Snoopy, You have me stumped with that one. I just had my bike torn down to change the Left Handlebar control switch.
(If you search my posts for "head light issue" you will see what I mean.)
I had all the plugs disconnected, the stereo out, the instrument panel out & I can't tell you for sure where it actually is. The only thing I can think of is the radio station display is above it so I'm thinking it's part of the stereo. But as I said you've got me on this one.
