I'm an idiot

I was having a good day welding in my spring relocation kits. Things were going great until I noticed flames comin from the trunk. I strongly advise that you make sure that there is nothing flamable around when doing frame repairs. I know I will from now on. No major damage except a burnt box that contained my front wiring harnesses. I am now in need of a headlight wiring harness fo a 1971 dodge demon. Can anybody help me out.
