How to rewire a project tonearm

Hi there music lovers 
 Recently I disassembled the tonearn of my project 1expression 2 turntable to rewire everything . Why ? The clips of the wire that go to the cartridge were breaking off .

I just recieved from England a new set of wires . Now I dont know how to get the wires threw the tonearm as they are so small and soft they just stick at some point in the tonearm and can't get them threw . 
Now that I check everything I think I am over my head as its going to be dificult to get everything together again . 
If any one knows something about this I will apreciate any help you might give me . Thanks guys , take care a be safe .
