I want to thank everyone: zstripe,richg1998,rrinker for all the info.The loco i purched on 03-15-2015 came in a new athearn box #89555.The parts sheet show light pins and a light pin socket under the main board,I'll trace the wires just to make shure.I have a project i'm doing now on a 4-4-0 American,so when i complete it i'll start this one,and post the install when it's completed.
