On my B373 those wires run straight out of the blocks without the crimp connectors. It looks like maybe the wires were all too short and needed a small extension on each one. Or did they move the block a bit and need the extra lenght? I can't believe that ALL of the wires they ran came up short and they needed those extensions. FWIW, the crimp connectors look good so if all is working, I wouldn't worry.
