Gtbarringer I helped put your repair pack together. There is some extra bits (wire and cable ties) and the blue wire is longer than you need so you can trim to length. I stole a wago connector as well to make it super easy.
When you wire in the replacement Gicar box take photos of the wiring of the old ones pins.
The short wire in the wago, is just to show you where the blue wire will go once you have cut the bad bit off and stripped the end.
