Need correct 2 pin plug for K4 4-6-2 loco

[OlddManWithHO]

All,

    Need correct two pin plug coming out of loco going to tender.  Wires are broken.

    For Spectrum item #54101 Pennsylvania 3750.

    I've order Universal plug from Bachman before but was too small.  Got a white plug.  Mine is orange.

    Order on ebay another 8 position plug to replace the wires with.  Again too small!  Bachmann DCC Tether (loco-tender) 6-Pin Plug (HO Universal) Connie-10548

     Is there any plugs you guys know about I can use?
