It looks like, electrically speaking, the one in the Ebay link will work. You need 11 wires. It has 11 wires. The 371 product code designates gold wing. It's uniqueness is probably the length of wires, which may be longer or shorter than your needs. (probably longer, don't gold wings have longer bars?) Do the gold wings have thicker bars? 7/8 or one inch?
I can't tell from the picture whether the gold wing wires are meant to route inside the bars or outside the bars, or,what your intentions are for wire routing. Some of those controlls already have the notch in them to run them outside. It would seem a shame to file a notch in brand new controls to run the wires externally, though you could drill holes in your present bars if they don't have them already.
The 77 Cb550 K3 controls have a block connector instead of the bullet connectors you require. It's possible to put bullet connectors on instead, if the wires will still reach to your connection point. I don't know if you have a F model or a K model 550.
