On 2005 and newer models, they're located inside the Smart Junction Box, and they're tagged as non-serviceable items (which means that they may be soldered directly to a board in the SJB). The SJB is under the front of the center console.

Here's the first page of the power lock wiring diagram, if it'll help:

Thank you for the info JPark. As I stated on the subject, the mod I am trying is to control windows with the remote, but know I do not see how can I take the signal from SJB (lock/unlock) put it on a PIC IC, with the up/down dirver window switches without adding another alarm. Any chance that you have the SJB logic diagram?, also I dont see the intreface between power lock/unlock swithces and driver door switches in your diagram, did you? Best regards and great suppport!

If I understand you question correctly, I think that I have good news, and you won't need to dismantle the SJB. There's absolutely no information about the design of the SJB. Ford guards those designs better than NASA.

First, here's the rest of the power lock system for a 2005-2007 E/M/T (including the first page again):

You could probably use the power window circuits, too:

If all you need is a signal that's +12V when the doors are unlocked (using Remote Keyless Entry, or using the key in the driver's door lock), you can take that directly from the RED with ORANGE STRIPE wire (pin 3 on the C2280C SJB connector). It's normally low, and +12V for about 1/2 second when the doors are unlocked.

The PINK with ORANGE STRIPE wire goes +12V for about 1/2 second when RKE is pressed a second time, unlocking the remaining doors and liftgate (although your 'scape can be programmed to unlock all doors at once).

If you also need +12V when the doors are locked (RKE or key in the driver's door), the PINK with BLACK STRIPE wire goes +12V for about 1/2 second when the doors are locked.

You can easily find these wires in the single harness under the driver-side kick panel.

To use any of these signals for direct PIC inputs, you should filter and isolate each of them first, because they may contain induction spikes from the motors:



And you're programming a PIC? Which one? I've played around with a 16F628, but nothing more ambitious than that (so far)...

I'll bet that you're trying to design a circuit to crack open the windows when the doors are unlocked.

JPark, you are the man. Where did you get the info, this is what I need. About PICs I have not much experiece, just small things with 12F509, 12F690 and now 12F629, but nothing complicated....just for curiosity I can't find where the 1088 cable (PK-WH) is wired to, can you?...

seems like there is a duplicated drawing as well (maybe there would be the explanation for the 1088 cable)

I would let you know if I succeded with this mod.

Yup, you were right about the third diagram (it was a cut-and-paste victim). It's now fixed. These are from Ford's service DVDs, which you can find on ebay.

The 1088 lock input circuit (PINK with WHITE STRIPE) is simple:
* Ground this wire, and the doors will unlock.
* Ground this wire through a 1.8K resistor, and the doors will lock.

Please let us know what your mod does. I'm very curious.

:D
