Hi all, im hoping someone can help me here I have a 1983 le mans scalecitric track and I'm wondering how to connect the controller to the track. I have the classic controller with the red tab that connects underneath the track but I do not know where it clips in. I'm not sure am I missing a piece for this. Can someone please send me instructions on how this is connected to the track Or where exactly it clips in? Thanks
