Hi. I need to wire my new Lionel Teddy's Hobby Shop to my MTH AIU. It has the somewhat annoying plug n play connector.....has a black, red and white wire. If I connect to an MTH AIU, will the lights be on all the time and the inside trains move when I activate the accessory? Or do you have to wire thru the Lionel switch which comes with the Hobby Shop. Lionel instructions say you have to hard wire the red and black to power, but do not mention what to do with the white wire and if you can control the two light/power features without using the Lionel manual switch. Please help!
