you'll find out soon enough if its dented enough.

i really dont recall the size, it was a little bit thicker then the factory harness wires. solder and shrink tubes to seal em. i got a 10 foot roll of wire at the parts store. then tapped the wires up to keep em tight.

do not try to cut the o2's plug off and make it longer, that wont work, theres a stainless steel wire that you cant solder to.
