New internal cable for Basilisk v3 mouse needed.

I need a new razer basilisk v3 cable (not a usb-typec cable, one for the mice with non-removable cables) to repair the mouse, and I tried splicing it and soldering the wires together, but I did a shitty job on the shrinkwrap and it won't insulate properly. I have all the tools I need for a full cable replacement, I just need to find a cable. I already tried to put an amazon basics cable from another mouse in there, but the connecter was too big. Please help me find a cable that I can order to get this repair done.
