    Now that we can finally fix pins on motors and sensor wires, what are the right parts to buy to fix these guys?

    We have plenty of motors with one pin missing we can now legally fix.

    What are the right names of the connector parts and where can I buy some? Any preferred crimping tools?

    Get one of their servo connector starter kits. Have never looked back. You want the "Futaba/J-style" connector housings.

    Those will fit and work, but to get the proper keyed connectors that lock into the cortex, you want the futaba style ones from the site I linked. Hansen's crimping tools are good as well.

    The fatuba female connector looked different from Vex ones as it had a "sheath" but the male ones have the little tabby thing.

    Now we can even make extension wires with the tab so they don't come out of the Cortex as easily! (although not exactly like for like)

    Is there a new rule that I missed?

    @jpearman Is there a new rule that I missed?

    I think he's referring to this one:

    R15a External wires on VEX electrical components may be repaired by soldering, using
    twist/crimp connectors, electrical tape or shrink tubing such that the original functionality /
    length is not modified in any way. Wire used in repairs must be identical to VEX wire.
    Teams may make these repairs at their own risk; incorrect wiring may have
    undesired results

    I know this rule was there last year, and I could imagine the years before possibly as well. Unless I'm missing another rule, I can't see anything new.
