I had issues with my smoke fluid filler. The manual clearly states you can use either the Lionel quick connect or standard wiring. I soldered two wires to my track accessory wiring bus, as I did with all other such accessories. I programmed it to my Cab 2, but only some of the functions worked. It did not pump oil. I returned it to my dealer for an exchange but purchased the Lionel plug-in. With all three wires installed, the accessory functioned as advertised. Despite the manual clearly saying you can use a two wire standard connection, all functions are not available with this connection type.
