Chris, it appears you need to make a cable that has "straight-thru" data but "crossover power" looking at your wire color description.
I would suggest using two jacks with 24gauge wire between them instead of trying to crimp the RJ45 connectors for ease of rewiring.
Sounds like you are adapt at making cables so try this:
Between the jacks wire pins 1,2,3 & 6 together.
Then wire pin 4 on jack 1 to pin 8 on the other and pin 5 on jack 1 to 7 on the other to cross the power. Then wire from jack 2 to 1 the same way.
This should have the appearance of connecting the blue pins to the brown ones keeping the correct polarity.
Good luck.
