There was a thread here a while ago asking the same thing. It may have been in the 'Conversion' category.
Here's some info..it's more about the sensors than the plugs. http://www.chevythunder.com/ls1_page_1.htm
You should be able to lay out the harness, and by process of elimination, figure it out. driver inj & coil plugs/pass inj & coils/ then, the short ones to rear of manifold..etc. go behind the manifold.
Are the sensors already installed? This would help match the plugs.

I just did a search for "IDENTIFY PLUGS" & also "IDENTIFY CONNECTORS" in the 'Conversion' section. This turned up a number of threads which help identify some of the plugs. Pls keep in mind that you have an LS1 harness.
When I gave my answer above, I had forgotten that my conversion harness had been stripped of alot of the wiring, therefore making my job much easier than yours. Hope this helps.
