Sockets and cables connection

[Devl]

Hello, i decided to refresh my bike, took it apart, repained rim, now trying to reinstal all wires and connections and there is one socket and wire that i dont now where to connect (my bad that didint marked and taked picture of it, and i didnt noticed if it was already disconnected). The wire is from battery negative cable (mine is 3in 1 cable) that goes one side to gearbox(starter negative) abd other side 3 connectors: 1 battery; 2 frame (under fuel tank); 3??? is my question.
And then i have one socket that is somwhere under the fuel tank, and its have I- kind 2 wires conection. Where to connect them ? Bike K1100RS. Thanks in advance.

Negative terminal on the bike only needs to go from battery to the frame.  The 3 way connection is just redundancy, probably in case paint or finish prevents current from getting to parts of the bike that need ground current....like a gearbox thats painted black for example. 

I dont recognize the connection style you have shown, is that connector on the same 3 way cable?  If yes, its odd that you'd get 2 leads coming from a cable that only touches ground.  Might be an accessory connector of some sort.

My k1100 only have a wire from negative on the battery to the engine block.  All the rest of the components just get their ground from the frame.  Of course my bike is a custom version, but the function is still the same for ground...as it is on all bikes.

The one with the 2 prong connector may be the radiator fan wire.

Another way to put that would be to stop and smell the roses.
