I have a AutoPage 850LCD alarm and the installation manual is not clear on alot of things for a novice installer. The manual shows for postive trigger door lock systems you connect the blue wire to the lock side (shold this be at the BCM)??? and unlock green wire at the (BCM). Then it says the wires run to the exiting door lock relay. I'am not sure where to go from here (not clear on the To Exiting Door Lock Relay). Any help would be great

Oh the truck is a 2002 GMC Serria SL with out security system but has power locks

Yes, you are correct. Connect lock and unlock at the BCM, white and light blue in the far left harness. Disreguard the "to exiting door lock relay", I think it meant to say "to exsisting door lock relay."

If you need any more help with your 850LCD, please feel free to let me know. I have installed a number of these, and they are very user friendly. The only thing that is confusing is the programming.

Also, be sure to ground the BLACK/ white wire (22 guage "optional toggle switch wire") if you are not using it for the optional toggle switch.

Good luck

Do you have to program the door locks to work or should they start working when the alarm will arm and disarm fine.

Thanks guys

they should work as soon as you hook them up. you may need to change some features such as "start lock"

but they should right away...
