If you take off the seat, and stand on the right hand side of the bike you can see the black plastic panel which joins the front fairing to the rear fairing. This is held on by one 10mm bolt, use a socket or phillips screwdriver to undo this. You need to pull this plastic piece quite hard at the rear near the pillion grab handles, and again quite hard at the bottom of the black plastic near the footpeg. The black plastic piece will then slide away. If I remember correctly, the indicator relay is the one closest the front of the bike.

Good luck!
