Can't find the timing marks

Hello, can anyone guide me to where I can find the timing marks on a 2.2 turbo? Trying to time my engine. For the 2.6, my Chilton's manual had a great blown up picture and diagram of the timing marks and their location. However, when it showed where they were on the 2.2, it had a zoomed in picture that would only make sense if you already knew exactly where it was. *sigh* So any help would be great. Also, it says to disconnect the electronic coolant sensor when doing the timing, but, again, doesn't say what it is or where it is. Where would I find that? I'm guessing it's the plug that goes into the thermostat, but I want to be sure.
Thanks.
