Car Alarms: 2007 Ford Ranger Alarm install, purple wire, ford ranger

Question
I am installing a UNGO S100 in a 2007 Ford Ranger. The first problem I am having is getting the drivers door to trigger the alarm when the door is opened. I am using the green/purple wire as indicated with diode. The other doors trigger the alarm when they are opened also have diodes.
problem 2 is I believe the door locks are a negative b type?
can you confirm and give me relay diagram.

Answer

DIODE DOORS This is better:

All Door Trigger  GREEN/BLUE (+) HARNESS TO THE RIGHT OF GAS PEDAL
YOU MUST DIODE ISOLATE BOTH TRIGGERS TO MONITOR ALL DOORS.

Positive trigger doors here. Use ONLY that output.

See if that corrects it.
