nearly completed re-installing my engine and components back into my springer.

Just had a quick google search. Just go to find out where it goes now. Looks like the coil pack has a plug in it

Have a look at this instructional pic by pic

Coil, I assume its a clean fit? I had and issue [fitment wise] with a late model Hypercharger, but I assume you have the same coil?

I may be late to the party , but it's not the connector for the "active air" is it ?

That's always flapping about after changing to a high flow air cleaner on "Aussie" spec ( ie International ) bikes.

Sorry I can't remember offhand the colours of that one right now. In hindsight they may be different sorry !

Double hindsight , just been out to the garage to look at mu own 2008 CVO Springer and there is a plug going into the coilpack

Fuck , I LOVE beer...

connector, I'm hopeless without a manual, which I read after damage done, like Ikea directions..anyway how did we get to beer. Now you mention it, I love beer tooo much.
