Remote start 2003 Avalanche

on the GMDL4, what wire color is for the door pin trigger.  the instructions are not clear.  Also if I connect this to the negative door pin trigger from the alarm/ remote start, will this work with all the doors?  

2003 Z71 avalanche

the door trigger wire from the alarm is green (-) trigger, connect that to the 457g , then the 457g has a gray/black wire that say's domelight input , connect that to the same color wire for the domelight on the bcm of the avalanche that's located under the driver dash.now connect the door locks, unlock (-) and lock( -) from the alarm to the 457g. now ground the black wire of the 457g to the driver kick, to the metal for a good ground, any other place you ground the 457g won't work or you'll have problems. now follow the program instructions to the 457g and you'll be set.good luck. p.s. the 457g will control the passkey too without cutting the ORANGE / black passkey wire. used it on a 2003 Silverado worked like a champ and saves you install time.
