why would you take the wheel off to relocate the turn signals?
but the bike on a jack and unweight the wheel and suspension, undo the top shock mounts and lift , this will leave the wheel on the ground and the fender in the air to allow access to the wiring and bolts holding everything in place to allow the relocation from the side of the fender to the lay back plate
tidy everything up lower the bike and do up the suspension bolts
