'04 GMC Truck, service 4 wheel drive

        I installed a Hornet 554 remote start into a 2004 GMC Sierra Diesel I used a passlock for the key and I also data Bus interface for the door locks and arm/disarm. I also installed a 528t for the wait to start light. 

      My problem is this,  when remote started the "service 4 wheel drive" flashs on the dash.  If the truck is started with the key everything is fine.  I hooked up 2 ignition and 2 acc. wires for the remote start.  This is all I can find.  Might there be another one? 

     Also if I lock the doors with the button on the door panel before exiting, then unlock the doors with the remote start remote it will trigger the Factory alarm.  Then I have to get out and put the key in the door and mess with both remotes before the truck will start.  Did I miss something?  Please help,  I have learded alot about this install threw this board.   Thanks for all the help..

  Thanks for your help, 

     I have since changed the wire that goes to the data Bus interface for factory disarm.  I had it wired to a constant ground when remote started and I switched it to a pulse ground.  Seems to work fine now. 

    But this "Service 4WD"  is bothering me.  I cant seem to figure it out..

       Thanks again...

     Yes this is correct, both orange and brown are together even when started with the key.  No problem if I start the truck with the key every time. 

    This might be something to help figure it out.  Once I installed the 528t for the wait to start light is when the problem accured. 

   I might have just figured this out.  I will check to see that all relays are on when "wait to start" is acctivated.  Maybe the alarm shuts one off during this.  Im not really sure.  I dont see why it would, but its something to look into.  I know others have installed the same thing on the same kind of truck with no problems. 

    I paid over 500.00 just in alarm and misc boxs (528t, databus, etc.) and traded laber to have this installed and had nothing but problems with it when I got it back.  My truck was in the shop 4 times to try and get it right.  I finally ended up jerking it all out and finding the wiring on the internet for everything.  I reinstalled it the other day, and fixed everything but the "service 4 wheel" that wasnt there before I installed the "wait to start".  Now that everything else works just fine im excited to finally be done with this project.  Thanks for all your help.....
