I have a bad ground wire in my right headlight which is making the bulb dull. Has anybody else fixed this problem? If so, please provide either a diagram, short instructions, or list of parts/tools needed. I'm fairly certain that I'll have it done very soon because of a friend who claims he can do it easily, but I'd just like to have a second opinion from somebody that actually has a Galant or Mitsubishi for that matter.
