NEED HELP Looking for the pin assignments for the modules on the splice pack 306. having class 2 issues. Help please?

Thank you! Much appreciated! It appears that the wire colors in the harness to the splice pack in the diagram differ from the the colors in my vehicle. I'll have to look into that further, but I have more than I had yesterday, Thank you again!

The splice pack diagram for sp306 that I have is the same as was posted. Are you perhaps looking for a different one ... sp205. where is the area that you are looking at for the splice pack?

Yes sir, you are correct! It's the sp 205 under the dash that I am looking for. also looking for the wire diagram of the class 2 Serial Data Bus showing the connections to the sp 205. I've seen several of these diagrams but never one for the 2006 Trailblazer. Some of the other diagrams were for Silverado, Tahoe, etc. All have different wire colors in the harness to the sp 205. If that makes sense?

If that makes sense?
Not sure if I do understand. Your original post indicated sp306 which is what was provided and now you are saying "sp205" and then mention "different cable colors problem". Back to my question... what splice pack are you looking for? You know that there is more than one splice pack... right?

OK, so I just bought this vehicle two weeks ago and trying hard to learn about it. I joined this forum, and I'm trying hard to learn to navigate it. It's the first forum I have ever joined. I know I have made mistakes in replying to post, and accidentally started a new thread, and you guys have not seen msgs or replies to you. You are probably figuring that out by now. I truly do appreciate your time and help. And I apologize for wasting your time. Yes I do now know that there are more than one splice packs! Best regards.
