Maybe reach out to KEF directly. I've had good luck with them and found them very professional and responsive. 732-683-2356 (USA) Good luck and cheers.
Thanks for the responses and will call Kef directly. I am redoing a pair of Kef 107’s and want to make sure that the wiring from the crossover to the speakers is right.
I Googled Kef 107 crossover. Got pictures of an old ebay? auction for a pair. I don’t know if it is what you need. I could not paste them in here. There was a picture of the backside of the board to help reverse engineer it.
