I was asked about how to locate the indicator wires when mounting Givi V35 bags on side racks. The Givi mounting bracket behind the taillight relocates the indicators further back, and if you try and use the existing holes on the fender, the wires aren't long enough.
I blocked those holes with plates designed to use to mount aftermarket indicators (search Suzuki Indicator adapters). I used a black bolt and washer through the hole so they look stock.
I run the wires underneath the taillight lens, which is where Suzuki run the wires on factory side bag setups. There's plenty of reach.
