Default MAF sensor HELP PLEASE!

I have a audi a4 AEB block and the person switched around the maf sensor so there are individual wires instead of having a pigtail hookup. My engine threw a MAF code and i need to put in a new MAF but I dont know where each wire goes. there are four, green, green/yellow stripe, yellow and brown. Which wire goes onto which prong? Could someone upload a picture of there pigtail or tell me which wire connects to which pin? Thanks

I assume that you just yanked the wires off of the MAF and didn't note where they were plugged on the old one? I don't have that car, hopefully someone who does can help.

No two of the wires were off when I got it and since it was throwing a MAF code I am guessing that its a possible the other two aren't even attached correctly. Yeah If someone who has a 1.8t AEB block please look under your hood to see what wires are attached to your pigtail on your MAF that would be great.
