Common Electrical fault causing UCB issue

In typical fashion I seem to have myself an issue, I need to know how to de-pin that green connector or where to buy a new one.
Been having intermittent airbag lights and brake faults for almost a week now and a battery reset usually did the trick but not this time.

I read on another forum about this and have ordered a new battery fuse from Renault Parts Direct (They are a pain in the arse to source as no where has any) but seeing as that green connector pin is looking a bit cooked I want to re pin it. Any pointers on how to do so? Cheers IMG_2209.jpegIMG_2210.jpegIMG_2211.jpegIMG_2212.jpeg
