Im intrigued with CAT5 crossover cables. I have a CAT5 cable with 568A ends. I want to transform it into a crossover cable and found the schematics fore a 568B end. Now all i need to do is rewire one 568A end and Im set. The problem is removing this RJ45 connector on the end. How do i get it off? I do want to replace it back on for future usage. Do i reguire a special device for removal and reinsertion?

I have 2 different CAT5 cables each with a deifferent looking rj45 end. The one RJ45 seems to be held in place by some rectangular block coming from the cable while the other seems to be pinching down on the cable .
