i did think about running it inside, but i do have my subwoofer wires running through there as well and it might get cramped in the well. Also, i think i am running out of space to drill in the firewall. I mounted my side neons to my body kit rockers, and for the front on i put the first and last screws on the bottom of my grill fender with the middle one on the little plastic piece in the middle connecting it in place. And for the back one i used the spare tire well and put 3 screws through them. For my neons i have little plastic suspender/hook things which i mount and pop the neon into. It's like a closed circle with a little opening which you pop the neon into if you know what i mean. Is there any way to run the wire underneath the car to the engine?
