Hey Guys

I am a little lost with trying find out where the third connector connects to, the other two I have connected but the third I am completely lost! I didnt have the pleasure of taking the car apart, my mechanic left the car in pieces after he found out that timing the Audi A4 3.0 quatrro is different from any other car so he just never came back (hint: don't use mobile mechanic for Big jobs)

So I got access to the special cam lock tools and finished it myself, but i am stuck on this connector? see pic


Please help
