Justifier pink gun MD, 3DO Lightgun

Hi guys, recently I have been fixing things that I forgot some time ago lol. Some of these things are a Mega Drive justifier pink gun and a 3DO lightgun. Both have damaged cables and where get as is. I am wanting to fix both so I came masking if someone have the diagrams so I can make new cables for them or even if someone is kind enough for helping me. It would be a good thing as some guns are just lost because of this problem.
