For the 48 2 ton I had the harnesses made at Narragansett Reproductions, in RI as well.
They make original (100 point) harnesses and will customize them as well. They made a main cab harness with directionals, 1 wire alt, and a volt meter instead of ammeter. Also added a branch for the automatic trans and it cost less than the high end plastic harnesses sold by the online suppliers.
Also made a rear harness for the 12ft flat bed to my drawings (original had 1 tail/brake light) with individual brake, tail, directional, backup and side mounted gas tank.
Looks original and their over braiding is great.
