how to safely remove wires from cartridge to change to new cartridge?

Hiya, well ive finnaly got round to ordering a new cartridge for my project debut 3 TT after a year and a bit of using the factory fitted jobby, ive gone for the ortofon 2m red as this seemed like the obvious choice. Ive read up alot and i am confident i will be able to insatll it and align it all up properly put my main concern is those 4 wires that are connected to the cartridge, man do they look fradgile! Do any of you have any pointers on how to remove them safely or is it just a case of gently does it? Would using tweezers be a good idea or should i use me fingers? Cheers.
