Hi everyone this is my first post. I've been searching the name of Rear light connector with no results. The only shop I've found to buy a brand new plug in a german shopt but it costs 25 eur, I think is too expensive, anybody know the name? or cheaper option.

Do you mean the plastic plug on the end of the wires that connects to the light fitting? I'd go down the local scrap yard and chop one off. If it fits in your pocket it's free

Yes exactly the plastic plug, sorry but I'm a newbie and I can't post images or url's until 5 posts.

Yeah I thought to go to scrap yard and pick up one.
