I'm not sure I follow but here's what I can gather from your pics....

If your slipring does not have the pins inside the connector socket on the face side (the one that faces toward you) then you need to order the correct slipring----the one for heated wheels.

Can you clarify what you mean by the connectors are too short? The connectors from the wheel plug into the face side of your slipring---not the back.

Lastly, in your 3rd picture, what is that that looks like melted wires in the center of the screen.

All the part numbers of everything you need to do this is listed in that walk through.....compare those with the numbers on your pieces and you'll soon find out if you have the right parts.
