Fusebox relocation/wire tuck

[Elsom-20]

Hi all, I've recently done a passenger side headlight wire tuck. It's basically complete, I just need to extend the 2 cables connected to the fusebox! They're both white, 1 with silver wires and 1 with copper. Can someone tell me or send me a link to the correct wires I need to cut and solder in please?

I have no idea what ampage or type cable I need!

Thanks all!
