Cable routing?

Installed my Innovate LC2 air/fuel mixture setup this weekend. Got the gauge and processor mounted and have the wiring all figured out. I am trying to plan for the routing and fastening of the big cable that runs from the sensor to the processor. The exhaust is not installed yet. Hoping to get suggestions and/or photos from one already installed. Also, which side should I put the bung in with an LD4B dual plane intake. Read somewhere one side runs richer/leaner than the other with dual plane intake.
TIA---DRO:)
