2009 Ford F-150 Door Trigger Wiring

The individual door pins are not +(POS) they are "open"

I am not showing any info on the dome light. This might be what Joe is talking about.

chev104275 -

I'm not familiar with the gray/violet wire at the Smart Junction Box. But I'll definitely check it out. I'm installing a Viper 5901. The green and blue wires out of the "brain" are the positive and negative triggers for the door functions. The blue wire shows (-) unlock and (+) lock, while the green wire shows (-) lock and (+) unlock.

I looked up a post on a similar install into a Ford Flex and the wires they show are the following: Power Unlock as Yellow/Violet (-) and Power Lock as Blue/Green (-) C2280C pin 17 [which is incorrect].

Reading through the Power Door Lock section of the 2009 F-150 Wiring Manual, I cannot find the Gray/Violet wire that you are referring to (there's a Gray/Violet).

KarTuneMan -

What do you mean the door pins are not (+)?  Would you please elaborate?

... I "tested" the Violet/Gray and Light Blue/Light Green and both emit a positive output when the Unlock switch is activated. Other than that, I'm afraid to keep tapping off wires in hopes of finding the right two.

Ahh Joe, I see what you are referring to... the gray/violet wire is indeed the all door trigger (pin 9 on the C2880A sub connector on the passenger side kick panel)

dome switch turned off!

Noted. I'll test that wire, and get back to you.

Where did you get the info on the proper wires? I've looked all over for those... I'll try them out. So something like this --->

ALARM BRAIN --> green and blue wire --> diode (with current flowing to connector -->) crimp to GY/YE and VT/GY?

Joe. No luck.

I'm getting a (+) output on both wires when I unlock the truck with the remote. I connected the wires with a diode as you specified and nothing either way.

With the blue wire and green wire hooked up to an LED, both LEDs light when I unlock the truck, but neither light when I lock the truck. Any suggestions???

The individual door pins show a VERY low voltage reading or NOTHING when opened, and ground when closed.

They need to be isolated, and "converted" to a (POS)+ trigger to be used.

There is a diagram out there somewheres.... I don't type well enough to put it down.

Okay. ...door triggers (right front, right rear, left front, and left rear) are wired properly to the appropriate wires and isolated using diodes... no problems there. It's just the door locks.

Let me try to explain further. Green wire to VT/GY, Blue wire to GY/YE. Diodes on each wire. Unlock displaces 0V on each wire, whereas Lock displaces 12V on each wire. Shouldn't these wires be emitting opposite charges depending on whether I lock or unlock???

The Door locks on your vehicle are 3 wire negative.  Following is a diagram for 3 wire positive.  There are instructions in the text that tell you what to do to make it negative.  According to Audiovox, you do have the correct wires.

3 Wire Positive Door Locks

This is one of the most common type of door lock switch configurations found in most vehicles. In most cases you will not need to add relays for this type. Most of the newer alarms and keyless entries on the market today have both positive and negative 200 ma door lock outputs that are usually capable of activating the factory relays. Should you need to add relays for a "3 wire negative" door lock system, just change both normally open terminals (87) from 12V(+) to ground. If your alarm or keyless entry has positive outputs only, you will have to connect the other side of the coils to ground  and connect your outputs as shown. The lock and unlock wires below refer to the switch wires, not the motor legs.

I was just re-reading through this. I thought I wouldn't have to do this though because I'm tapping in BEFORE the relay... or am I after the relay but before the actuator???

Wow. I think I answer my own questions after I post them here and re-read them a few times... the blue and green wires emit both positive and negative signals depending on whether you are locking or unlocking the vehicle, correct? So just hook up the appropriate wire to the (-) lock output and the appropriate wire to the (-) unlock output and VIOLAH?! let's go try and see!

THANK GOD!

Hahaha. Thanks ALL for your help.

If anyone has any questions about the wiring of a 2009 Ford F-150, let me know and I'll pass the schematic/diagram/whatever-you-want on to you. It was a slow 4-day project (used a lot of electrical tape and a whole lotta wire loom) but I'm successful. I'd say the feeling of completing this complex alarm system is better than the "other good feeling in life", haha. Thanks again fellas.
