I'm looking for the 2003 Celica GT Alarm, remote starter and keyless entry wiring locations and colors. I have 2005, but am not 100% sure they are the same. Thanks!

Hi again guys,
I'm still having some problems. I diode isolated each of the door triggers in this car and wired them to the negative trigger input of the alarm but the alarm will go off around 5 seconds after i close the doors when I arm the alarm. I think it has something to do with the timer for the dome light, but haven't had time to verify that yet. Any suggestions would be great.
Keyless entry and whatnot works fine and I have the window rollup modules working fine.
I've only ever done a remote starter once before and am having a few issues understanding what has to be done in this car for the remote start to work.
The car has starter, ignition1 and ignition2. My alarm has only ON, START, and ACC. ACC im guessing is a switched 12v that is on when the car is on judging from the diagram here. Start and on wires in the diagram go to a picture of an ignition with a key next to it. So I'm assuming one is to trigger cranking and one is hot when the car is on, but I haven't had time to meter each wire yet.
Any help on how things have to go would be greatly appreciated.

I forgot to mention its an alarm/remotestart combo. Sorry if there was any confusion in terminology.
