[Dead Parrot]

Since it looks like a bottom up build, I would think about adding a larger junction block. Better for adding newer accessories. One like this can be found in salvage yards on 90's era GM trucks. Similar can be purchased new. One advantage of the yard block is you can often include several wires with the proper sized ends and with factory assembled fusible links included. A lot of the alternators on this era trucks were in the 78~100+ amp range so the wire is already sized properly. In my pic, it is the easy to spot red wire with the alternator boot near the end. IIRC, this all was priced as a "Misc Electric Part" for either $5 or $10.
