Aha!

Merci. Was sure it was something unimportant since the bike is running fine.

Shouldn't it be showing a fault code if nothing's connected to it?

Yes, unless the error checking has been turned off (or it is a race ECU)

I turned it off in the ECU.

Pash - used your circuit to wire in my heated grips the other day - excellent stuff!
I wired on the grey plug to the end of it to make it liek the accessory socket - figured it'd be easier if I need to go back and change anything.

Cheers though!

That's not for the exhaust servo. (which on a stock 12STT would be under the airbox.)

That controls the intake servo found on Japanese models.

That yellow/green wire loop is for convenient spark pickup when dyno tuning.

Wrong......that IS the exhaust servo connector ......if you follow the harness from the airbox lid, it plugs into that connector

Please dont bother arguing, I've removed 100's of those short harness's and disabled the codes in the ECM when fitting aftermarket zorts.

Hi jos51700, welcome...

Yep you are right, Buell call the Yellow/Blue loop the "Dyno Loop"
