Tone arm plug in RCA cable?

I have a tone arm with a connector that plugs into the bottom of the arm to get the L/R channels from the stereo cart. 

There are currently going into a Sumiko Premire PIB 1 box on the side of the deck… The RCAs going to the phono stage are then combing off of that “break out” box.

So a handful of suggestions of phono lines to come off the table would be great to have.

Or do I just get some thin silver wire and twist up some, as they only need to be maybe 10” long (if even that long),
