Need some help on replacing some exterior light harness/wires

[zenkii]

I need some help with replacing the whole light harness/wires which leads to all of the exterior lights. This includes, headlights, cornerlights, foglights, bumper and side bumper lights. I am wondering if anyone have done this rewiring process before because the harness is pretty long and heavy... I'm doing this because it was in a collision and it broke the whole left side of each light harness(except headlights). Anyhow, is there some expert on body work, if so how long did it take and whats tools or info's required? Or is it just too much to hassle and should bring it to the bodyshop? Thanks
