Running Nitrous Line...

Well I have all my solenoids mounted on my car, and now I'm going to run the nitrous line from engine bay to the trunk. Are there any holes in the trunk I can run the nitrous line through?? Or will I have to drill a small hole?? And what do you guys attach the nitrous line to the bottom of the car?? The fuel lines?? And do you guys just use zip ties??
 
i run my lines with the fuel lines and they are just zip tied. and in your trunk there are some rubber plugs that cover holes in you trunk and you can just pull that of and there your hole. there about a inch in diameter
