Help pls. I am working on a 2009 Ford E350 E-350 econoline cargo can. I cannot find the negative door trigger wire.
Vehicle Wiring page gave me this:
DOOR TRIGGER GREEN/PURPLE (-) @ DRIVERS KICK PANEL or SJB, GRAY 26-PIN PLUG(C), PIN 14, SEE NOTE #2
But the best green purple wire I found gave me ground signal ONLY when the driver door is opened, not the passenger, rear, or the sliding door.
Where is the 26 pin plug anyway and how to tell which is pin 14?

I tested the door jamb switches. Their non-black wires are all 12V when door is closed and no signal (or ground?) when door is opened.... so that is not a "normally closed door trigger" that I could have otherwise used an Omega AU-NCT module.

I could not find much info on alarm installation on this vehicle. Maybe no one install alarm + remote start on a cargo van?
Can you please help?

The GN-VT wire at pin 14 is only for the driver's door. Look for a WH(pin 2); GN(pin. 3); YE(pin 15) for the other doors. They are all at the same end of the connector.
The SJB is the interior fuse box located to the left of the brake pedal (in most Fords).

Correct. Thanks for confirming that.
End up I have to run wire to each door jamb switch. I think I got it working now.

BTW, I made a connection mistake. Please ignore the sentence:
"I tested the door jamb switches. Their non-black wires are all 12V when door is closed and no signal (or ground?) when door is opened.... so that is not a "normally closed door trigger" that I could have otherwise used an Omega AU-NCT module. "

Ok. I took me 2 days because I am not a pro and the info for a 2009 Ford E350 (Econoline) V8 gas engine cargo van is quite scattered.
The door trigger is the most challenging. It is ground when door is opened. But the BCM (Body Control Module) also sends out ground signal for unknown reason, triggering the alarm. So, using diode is the only way to resolve the problem:

2009 is different than 2007. It is a generation change starting 2008.
2009 does not have "normally closed door trigger". You do not need omega AU-NCT. You do not need to use resistors.

Normally Closed Door Triggers

Oh, don't assume E350 is same as the F350 truck.
