This video shows the general installation process. Keep in mind, every van is different, but the process is similar.

1. Locate Wires in Door Latch Assembly: Begin by finding the latch assembly in the door. Follow the wiring from the latch and carefully open the loom, as you have already started.

2. Test Factory Motor Wires: Use a digital multimeter or a 12-volt test light to identify the correct motor wires:

• Set the multimeter to DC voltage.
• Ground the black meter lead to a reliable ground source.
• Ensure all doors are closed or latched.
• Probe each wire individually while pressing the remote lock/unlock button or using the door lock switch.

3. Connecting Wires:
Blue and Green Wires: Connect these to the motor wires you identified.
White and Black Wires:
• Connect the Black wire to a bare metal ground, either on the door or to a known ground wire.
•Connect the White wire to a 12-volt ignition source, often located at the power window switch. This wire powers the windows and ensures they work.
• Alternatively, you may route the White and Black wires through the door boot into the cab area and connect:
 -White wire to the ignition switch or fuse box.
- Black wire to a good metal dash frame.

4. Note on Safety and Function: While the M1+ lock will operate with just the Blue and Green wires connected, the White and Black connections add a safety feature. When connected correctly, the White and Black wires prevent the lock function from operating while the vehicle is running, ensuring safety if occupied.
