Anything I should know before...

Got an 1 expression 2 turntable from project that comes with the 8.5 " carbon fiber tonearm . Some of the metal clips on the tonearm cables broke off so I'm going to have to fix it installing brand new cables with their corresponding metal clips that go into the clips on the back of the cartridge 
 The turntable comes with rca connectors on the back where I asume goes the other end of the tonearm cable . The cable runs the full length of the tonearm inside.

Is there anything I should know before starting the job ? Thank you guys in advance for your help on this matter guys . God Bless and stay safe .
