Auto Reversing Trolley track number 44547

What kind of plug connects the hard wired track power wire to the electronic reversing controller.  I am trying to make or find an extension cord with compatible male and female connector ends.

I found what I need in an electronics store.  The product is a "4 pole aux extension."  They are normally used with audio equipment.  Bachmann used a 4 pole aux plug to connect the track to the controller.
