i have a 99 yukon 1500 4 door i cant figure out how to install the code alarm ca 1151 correctly .im an electrician but dont mess with 12 volt stuff unless its radios or amps. i got the alarm to lock the doors but not unlock and cant figure out the whole door trigger thing, and i think its only going into passive arming and not just regular arming. please help! a whole step by step pic or instructions would be nice.

Your truck has the Passlock2 immobilizer system. Your will need to bypass this to enable a remote start. Did you purchase / install a bypass module ( or use the relays / resistor method) ?

The door locks on a 4 door should be Type A (+). I am not familiar with the CA 1151 and don't know if it can directly connect to this type of lock system. The best way to control the locks is thru a DEI 451M Door Lock module. They are available "online" for under $10. The 451M Install Guide is posted in the Downloads section.

Bulldog lists the All Door trigger as :

DOOR TRIGGER PURPLE (-) @ HEADLIGHT SWITCH

Locate and verify this wire with a DMM and then connect it to the CA 1151 (-) Door Trigger Input wire.

Soldering is fun!

The CA 1151 has onboard relays that need to be wired to support Type A (+) locks. Follow the install guide for 3 wire Positive switched locks.

From the CA 1151 Install guide:

3 Wire Positive Switched Door Locks:

Connect the GREEN/ BLACK wire to the wire that provides a +12 volt signal from the factory door lock switch to the factory door lock control relay. (LOCK Signal (+))

Connect the BLUE/BLACK wire to the wire that provides a +12 volt signal from the factory door unlock switch to the factory door lock control relay. (UNLOCK signal (+))

Connect the VIOLET and the VIOLET/BLACK wires to a +12 volt battery source. (+12V Constant in the car)

The WHITE/ BLACK and BROWN / BLACK wires are not required for this type of door lock/unlock system.
