PCM wire locations... trace harness to pinout

So Hello all... I searched and searched and finally found the pinout for the 4.3L v6 (not easy) many threads with the 5.3L but anyway I finally have it. My son wrecked the truck and some of the wires were damaged/cut we are in the process of soldering them all back but ran into 4 of same color and no way to trace them to the wires in the harness. I found the attached diagram and was wondering if someone can tell me what the right hand side of photo is so I can trace the wire to pin#:
46 to 15
47 to 16
48 to 17
49 to 18
