Headlight Problem

My 03 SL500 had the RF low beam go out. I trouble shot whether it was the bulb or not. I replaced the bulb with the LF bulb which worked. It did not work in the RF. So I switched igniters. The RF ignitor worked in the LF. So I switched ballasts. Put the LF ballast on the RF headlight and nothing. I took the working ballast off the RF headlight and put it back on the LF. Now the left front doesnt work. I am thinking there is a short in the RF headlamp internal wiring. My Icarsoft shows both ballasts not working. Any thoughts or recommendations anything I missed?

Yeah check your wiring . There are some gnarly pictures showing the wiring with the insulation falling off in chunks.
