If they haven't been pulled yet then mark the ends
(like by nicking insulation 1, 2, 3, 4 times at both
ends of the wires).
If they are already pulled through, you could twist
two of the far ends together and use an ohmmeter
to determine which two, at the main panel; mark
wires at main end. Then untwist the far end and
retwist one of the original two to a different one;
see which one you still ohm out in a loop, call that
one neutral and mark both ends accordingly, etc.
Will take a while but you can dope it out.
