Power commander engine light

[adamn58]

I just installed my PCV today at my buddies and then rode the bike home.  Noticed the check engine light about a mile from his house and thought it was weird.  I rode the bike home with no issue and it ran great.  Any idea what this could be?

I did have a spare plug on the left hand side of the bike but could not find the home for it after an hour searching.  Assumed it was a diagnostic wire.  Could this be the issue?

 Maybe it goes here?

I think that's exactly it!  Thank you man, I was trying to hook up all the wires before the airbox went back on.  Genuinely appreciate the help!
