Before installing my insert I need to connect the plug to the wiring, it a winterwarm small and the manual isn't very helpful with this and when I got it or was already disconnected, I think I know how to do it but thinking and knowing are two different things so I though I'd post here. Here are the pics I took, the hot wire and neutral on the cord both have male connectors and the ground is a female connector, where do I connect them? Thanks
