Mystery Connector

I was putting the fuel rails back together and noticed that the attached plug had become disconnected. It is attached to the main wiring harness that runs along the frame. It is not the plug for any of the injectors or pressure sensor? Any ideas? Of course I obviously do not have a wiring diagram...
Thanks,
J

Hi JCW,
It is made up of three wires. One Green, One Brown and One that is Blue/Black stripe. I am hoping the wire does not go in the direction of the front tire. There is one other wire from that same main harness that goes that direction under a plastic plate/cover. Not even sure how I would get in there.
Thanks for looking,
J

The ignition coil connectors are three wire like that and include a green and brown but with secondary stripe. Did you check if one came off the ignition coil just infront of the fuel rail?


Addendum...
My second coil is

Green/Black- 12V (or more) power (?)
Brown- ground (N)
Black/Blue- ECU switched ground (?)

Maybe off something on the air box?

So I called the dealership and they said the wire is from one of the ignition coils - you were right JCW. I am not too confident about removing the radiator to get at the coils, especially since you need special tools. I may just trailer the bike to the shop and have them complete. This whole job was just an attempt to replace the fuel line and has really gone to hell and a hand basket. I guess this is one of those live and learn deals.

Thanks for all your input guys,
J

Update - rather than give up I went back out to the garage and pulled the fuel rails again to gain access to the area under the front of the frame. I was able to use a crow bar to pry up the plastic cover just over the spark plug coils. I then used my long needle nose pliers and was able to plug that sucker in. Re-assembled the fuel rails and have the air box back on. Hopefully I will be able to complete the rest of the assembly tomorrow.
Later and Thanks,
J
