Here is the diagram,It is always a good idea to only disaasemble one side so you can use the other side as a reference,I also reccomend using a set od brake pliers,they will the disassembly and reassembly much easier.

The only way I know of to get the diagram you are looking for is to acquire a "build book". Even dealer service manuals don't have this diagram. I got one from faxonautoliterature for $49 plus shipping. A better bet would be to find a spot on either end of the leak where you can work on it easily and work from there. Hope this helps.

the best advice is take your vin # to the GM dealer and they can put it in the computer and print out a picture of all the lines and where they go,they will do this for free,hope this helps.
