Wire Routing?? (Cab & Engine)

I got my switch-pros in and I have started the wiring process but have hit a few snags...

1. Are there diagrams that outline safe routes when it comes to running wire harnesses through the engine bay? I am concerned that I may route a cable to close to something hot or in a bad location. In my case, I am running my ARB compressor harness from the passenger side over to the battery and Switch Pros module.
2. For those with ditch lights mounted above the hood, I am running Baja Squadrons on Victory 4x4 brackets and the wiring harness does not seem to reach both lights and have enough slack to get back to the Switch Pros (mounted next to the battery).
3. What is the best way to route the Switch Pros wire through the cab to the shifter area? I have searched on the forum for wire routing but cannot locate anything specific. Is it just a matter of taking apart the dash until the route is obvious?


Thanks for the help and any feedback!

 

If you're really motivated you could drill a hole and use a bulkhead fitting. I just used a rubber grommet that surrounded a factory harness. I can take a closer picture of the exact spot tomorrow but it's a fairly large grommet just outboard of the brake booster and behind the ABS pump.



Here is the same grommet but on the passenger side:



From the cab it is at a level just above the foot pedals.

 

Thanks for the help. I ended up running the wires across the rear of the engine bay and around over to the battery.

 

I ran my compressor from passenger side to Switch-Pros under the rubber seal above radiator the same with my a pillar lights.
