Plug and play - Headlight Relay Kits

I just installed mine the other day, works great! I have had this hanging around in the box that it was shipped in for months, so the other day I figured that if I couldn't go to the car show, I would install this. It only took me about an hour and a half, and it fit perfect. I'm just wondering what to do with the old headlight plug on the passenger side? Did I miss something in the instructions? I just tied it up and put some electrical tape on it and tucked it down where it can't be seen. Mine is in a 64 Dart GT.
