The Bk/R on the MC18 (all models) is the 12V feed to the light/multi-function switch on the left handlebar, and will be live when the IGN switch is in the ON position, regardless of the setting of the kill switch.

thx andy it is a mk2, i didnt quite understand the last part of post, this black and red wire connects at a juntion that comes from the m-max box. the wire has been cut very cleanly where does it go .... its also quite long about 10 inches long, im worried as this is live wire.

i would also need help locating throttle cable, front pv cables and the little unit that tells people you are using the front brakes.

the reason that i have so many probs is this bike was stolen and recoverd and they really had a good go at it, they removed the alarm sysem from the bike and cut some wires away from the fuse box it looks like.

im really stuck so thanks again.

badly
