05 Chevy Malibu Maxx alarm/remote start

I have found the bcm at the passenger fuse panel. The wiring information provided to me does not relate with the plugs I see. One is body, and there are two others labeled delphi. I am assuming all the wires I need for an alarm/remote start would be on the body plug. I have not investigated yet, and thought that someone might be familiar with newer chevys. Thanks, Laura.

Here is the story... the directech info says you can get ign and acc wires at bcm, but I tried and did not work for remote start, only for alarm go to the ign harness for brown and pink. Now on to the bcm. Three are there. Top, right, and left. Leave the top one alone. The door triggers, trunk, locks, and brake are all in that plug. Now see all the wires going into the fuse box you see the thick red white... That is constant. If you have small hands you can poke around and find another thick wire that is constant as well. I have used just the red before and had no problems. Any othe questions? Email me... Knowledge@tmail.com   that I have access to at all times p.s. I work at gm dealer so I am pretty familiar with that car
