In need of wiring install tips for Vandemon exhaust before i start

Hello i am about to install the Vandemon exhaust with the quiet and loud switch.. I been looking over the instructions and it said it's easier to mount the switch to the RHR Rocker Bolt but it doesn't show where that is on the instructions.
As far as going under the fuel tank per the instructions is it easier to just fish the wire underneath and just loosen the fuel tank? Any tips or anything you would have done different if you did it a second time?

Alright guess im on my own

Hello chadster,
You’re going to like this exhaust system……
I have uploaded photos of my install,
The switch I mounted on the left side on the bottom corner of the air plenum. I bent the bracket and painted it black.
I didn’t use the plastic switch that came in the kit I ordered a metal switch of higher quality.
I soldered all connections, and used heat shrink tubing.
(Research specs on plastic switch for upgraded replacement options) your choice….
I mounted the wiring harness under seat in the cell phone cubby.
I installed heat shrink tubing and used insulated wiring clamps to protect the wiring around the swing arm.
Let me know if you have any questions……
With the free flowing air filter installed, Penner tune.
The low end torque is outrageous, and It pulls a lot harder now to redline.
The traction light always flashes now. I’m not a small guy, @ 6ft and 250lb.
Good luck,
