This is embarrassing. Four or five years ago I installed several two-light (2002) N.J. International signals and used NCE SwitchIts to control the red and green lights. I know I received a wiring diagram or some other form of advice on how to wire these signals to the SwitchIts but I lost a hard drive and can't find those directions anywhere. Can someone tell me how to wire the two-light signals to the SwitchIts? Any help would be greatly appreciated. ....Tom
