Which wire is ground?

Molex 03-09-1032 CONN RECEPTACLE 3POS .093 https://www.digikey.com/produc...1032/WM1332-ND/61321

The Hot is the center pin, and the Common is the bottom. The top pin is only used on the ZW-C transformers for jumpering a brick from one channel to the next in line.  The common is the ridged lead on the cord, the hot is the smooth lead.

Thanks John!  Is that 1 part number everything I would need to rewire the connection, assuming I'm starting from bare wires?

You need to go to the bottom of the page and get the matching pins.

CONN SOCKET 14-20AWG CRIMP TIN

Cool beans to fix the wire to stock. I disagree with folks who cut off the connectors. And especially since Lionel has the mating connectors available.

Cutting off connectors on PoHos for example,and soldering on spade or ring lugs, enables one to easily connect to the screws or binding posts of any railpower device in the Ogauge world and rid oneself of unnecessary male and female connector clutter.

However, just my experience, I understand it takes different strokes......................!

The mating connectors are dirt cheap, and you can easily fold these with needle nose pliers and then solder them for security, they're big enough to deal with. 

My thanks to all who replied.

I am using several PowerHouse transformers which will sit on an old TV cart.  The connectors will be useful when I need to disconnect the cart and roll it away to work on the power distribution panel.

OK, the Digi-Key page is super busy (aka cluttered), so please check this list for me.

(Qty = 1) WM1332-ND

Actually, you need the socket connectors for the transformer, the pins go into the mating connector.

One of these WM1332-ND Connector Shell. and two of the WM1101-ND - 0002091104  Molex CONN SOCKET 14-20AWG CRIMP TIN for each transformer connector.
