Since the WIU will come with a USB cable to connect A Rev. L TIU to the WIU, everything else that you listed is just what you need, with one exception.
The Lionel PH 180 has a Molex connector, not a barrel jack. You have three choices as to how to connect it to the TIU:
- Cut the Molex connector off the PH180 and connect the two wires directly to the TIU's Fixed #1 Input channel terminals.
- Purchase an adapter cable from Lionel (don't know the part number or the price) that will convert the Molex connector to a pair of bare wires, which can then be connected to the aforementioned TIU input terminals.
- Make your own Molex adapter, as I've done for several PH 180's. You'll need the following from Amazon:
The advantage to the last two options is that you leave the PH180 intact for a future application that requires the Molex connector, or in order to facilitate reselling the item.
