When running the wires inside my new handlebars the metal pin broke out from the connector on the right side controls. 2 wire plug only using only one wire it's a grey/white wire on my 2013 fat bob. according to the manual it's for the ignition kill switch which makes sense. I'm waiting for the new pins to come in so I can put the connector back on. but for squibs and giggles i flipped the switch and the fuel pump kicks on and primes and the bike will crank. This doesn't seem right, without the switch in a circuit shouldn't it not run or crank at all? Just wondering if there was a good reason for this or If i was just crazy

 

The two pin plug only uses 1 wire. All your hand control functions are running on the other four pin connector. The kill switch functions with a single wire though.

 

That much I understand. But it still functions perfectly normal but I've got the connector in my tool box while waiting on the new pins to come in.

 

Oh I see the problem now. Running without this connector is probably not safe because your kill switch likely will not work as intended.

 

CryingJoker, it appears that you are not the one that is confused...

 

I`m a little confused about this also...I looked at a wiring diagram, and can only see the one wire going to the kill switch.

My question is; how does a switch work with only one wire connected to it? Is the switch body grounded to the handlebar?

 

It must be referenced to the ground wire on the four pin connector.
