Lionel 169 Controller

[willy w]

Hi

I have recently acquired a Prewar # 227 Switcher with Magic Electrol couplers and I have a 169 controller but no instruction sheet. I believe I understand the basics of how the system works but I just wanted to be sure that I hook the controller up correctly. I'm guessing that it probably hooks up like the old Lionel prewar whistle controller. Can anybody let me know if I'm right?

Thanks [e-mail]
