LOCK WHITE/ lt.green or WHITE/ red In driver's kick or BCM   - 
 The Body Control Module (BCM) is located behind the fusebox under the driver's side of the dash, against the firewall. These wires are located in the plug on the left side. A negative pulse through a 1500 ohm resistor will lock the doors and a negative pulse through a 250 ohm resistor will unlock the doors. If the vehicle is equipped with a factory alarm, substitute a 4020 ohm resistor to arm/lock the doors and a 665 ohm resistor to disarm/unlock the doors. Relays should be used, see the DOORLOCK diagram.

Yes .... the double pulse IS a programming issue. Somehwere in the programming menu should be instructions on how to set up double pulse. BUT.... it's poss. that your unit will not do "double pulse"
