The harness goes from the right grip to the nose fairing, via the center subframe strut, over to the right along the nose subframe, up to two plugs:
The two plugs to be removed are the ones pointing down in this drawing, just under the rubber grommet that receives the nose fairing's mounting stud:
A lot of zip-tie cutting. In theory, if someone else hasn't rearranged things in there, you can reach in and disconnect the plugs, then draw the harnesses out. If you have speakers, its more of a pita to reach around the housings. You may want to consider removing the windshield, dash and dash cover so you can remove the nose fairing fasteners to allow you move the nose forward a few inches to get your hand down to the plugs from the front.
