Prostart CT-3400TW door lock problem

<<<<  I attached the arm and lock wires to the lock and arm wire and the disarm and unlock wires to the disarm and unlock wire of the GMDAA bypass module.>>>>>>>U stated (plural) arm & lock wires?  disarm & unlock wires?U should only be connecting the Lock & Unlock wires from your RS module to the Purple / White & Orange wires on the GMDAAWhen U finish wiring RS & GMDAA, plug units in, make sure everything is plugged in and connect the ORANGE / Black wire of the GMDAA to the OBDII LASTMO

Don't Learn from Others Mistakes

You Might Be the One That Knows.

2002 GM fullsize trucks are not ClassII compliant... therefore, the doorlock portion of the GMDAA will do diddly .   Locks are available at the BCM, located underneath the steering column, light blue and white, positive pulse, located in the left connector (the widest one... I can't remember the exact plug color... I think it's the blue connector. I just know where it is). You may also have to do disarm, it is light green, negative pulse, in the far right connector (Brown???). You will need to use two relays on the unit, as it does not have positive doorlock outputs (unless something has changed recently on the CT-3400). Pin 30, pin 85 on relays- 12V Pin 86-lock, unlock on other relay pin 87- lock or unlock output to BCM. Gus Wherever I go, that is where I end up......

I follow you on the relays for the locks but what about the factory alarm or does it work with the locks? Thanks again.

Does the arm and disarm require a relay or can they connect from the remote starter directly to the BCM. Thanks again.
