Any photos/tips for wiring this up?

[evan9eleven]

Tried to search but am not having any luck.

I'm looking for tips and photos on the best way to run wires between 1) a dash switch and the fusebox, and 2) the fusebox and the engine compartment. The install will be the electrics for controlling my homemade valved exhaust.

I'd would like to disassemble as few things as possible, so it would be good to know if the switch-to-fusebox wiring can be fished through under the dash. Also good to know if the oddments tray next to the driver's seat is easily removed as a path for the wiring to the back of the cockpit. And finally, where to find a grommet to sneak the wires through to the engine bay.

Thanks for any and all help!
