Anyone know how to bypass the security module in a 98 ranger?

My friend caught it on fire working underneath. He was welding and now my rear lights don't work at all. No turn signals, brake lights, nothing? I tried to run another system out of a Windstar but it was all wrong for this set up. If anyone can give me any info on the easiest way to bypass the system I would greatly appreciate it. Other then that the truck runs and everything else works but windows.

I would make sure the taillamp harness is plugged in... welding around the rear bumper area were you?
