Wiring in a larger alternator

[PbFut]

Something to keep in mind. The factory battery meter looks at voltage at the alternator and the fuse link block. Changing length or gauge of wire between the two will affect the sensitivity of the guage. Adding load at the fuse link block will affect accuracy as the added load at the block mimics a charging battery. You appear to be doing things correct by modifying the wire from to the main splice in the harness to the alternator. Just be aware that that main wire from splice to fuse link block is not as simple as it appears relative to the battery meter functionality.
