K-Line or Lionel A5 tether connector

I have a badly broken tether for a K-Line PRR A-5 0-4-0. It appears they are NLA at Lionel and Trainz doesn’t show them. They have a 4 wire thats close (no cigar) but not a 5 wire thats required.

Anyone know of another source or what the 6 pin part is that fits into the engine?

This is what the 4 wire looks like. The 5 wire has all 4 positions filled on the JST connector.
