What does the white wire clip to?

Everyone I did some work and took some pics so there is a clear understanding of where I'm at and what happened. You can see the fuse link connection at the firewall that burned out. There is some melted plastic where the fuse link plugged into the bulkhead connector. You also can see how my fuse link popped. Lastly I took photos of the red wire running to cluster I tried to ground off of and where the black ground wire is anchored. Should I replace the whole clip that snaps onto the bulkhead connector?
