Lionel 115 Station wiring!!

How do you wire up the 115 station without using the train stop control. There are 3 nuts on the base. Which nuts do I use so that just the 3 light bulbs light up using variable control on my Z transformer?? Basically, I just want the station to light up on seperate voltage from Z. And not from track power or the use of lockons, I want direct power from Z transformer. Any help will do. Thanks.
