AudiWorld Forums - ENGINE HARNESS CONNECTIONS - 2003 AUDI A6 2.7T QUATTRO

A guy on craigslist recently gave me a 2003 Audi A6 Quattro with a 2.7t engine with 150,000 miles on it. It was overheating and he didn't want to deal with it anymore. I gladly took it off his hands and proceeded to work on the car. I had no idea what I was in for but did the valve cover gaskets, cam seals, alternator, battery, plugs, one coil, both water pumps, replaced some vacuum lines, timing belt, thermostat (and housing), air filters, etc. I figured I "might as well" since you have to basically take the front end of the car off to do anything (at least I did...probably a rookie move). After doing the job I put everything back and here is where my problem is. I have no idea where 2-3 of these plugs go. There is one "extra" towards the front of the engine when hooking up the injectors and coils and then the same when going to the back on the passenger sidee. If anyone has a schematic they could share of the engine layout and sensor diagram that would be great. I would appreciate any help.
