OK, removed the back seat and panels to gain access for routing the wiring:
It was just easier to unbolt the upper section of the rear seat than line up and remove.
I have the rest of the harness wired up ready to go. Found a location for the controller, and have some rivnuts ordered for the smaller size. Gonna look nice!
I plan on routing the hose on the inside but before I do that, I want to do a test of the electronics and make sure they work as expected. Once I've confirmed that, then I'll route the fuel line and tap the lid...
