electrical gremlins are back

I pulled the the bulkhead off, there was no melting issues, but the wires are old and worn so I thought using the new wire in the MAD bypass would be a smart idea. I have a question though. So i pulled the old wire going to the alternator out and the wire from the starter relay to the welded splice. How exactly do I put these wires together? In the MAD article, it shows them coming together with taped wrapped around it into the fusible link. Just need clarification on how to splice these together. Also a 16awg fusible link seems kinda small for this doesnt it??
