Power door locks using doner car parts.

Work at a service type business that uses Ford Focus wagons ( going to have to switch now that they have stopped making the wagons ) for 300K plus until we smoke a deer or the cost of repairs is more then the cars worth. So I now have the chance to strip anything I want out of a cast off 04 Focus. Could I make the power lock system work in my 65fb with out reinventing the wheel too much? I have the door fobs and can be as destructive as I need to harvest parts. I would think I could get a wiring diagram to help me figure out the wiring. Worth the time? Anything else that would have application to a vintage stang?
 
Post a pic, but my gut is YES take those solenoids. I've done this swap many times from just about any car you can find in the junk yard. They are basically push/pull solenoids. All you need to do is tie the plunger to your door lock rod and then wire it up with relays. I made a schematic up a few years ago, but not sure where and on which hard drive I had it on. I'm sure you can find a good schematic on the net. If you have an alarm, it's pretty easy to control them with the alarm remote.

To tie them to the door lock rod, all you have to do is clamp them to it in the same direction and mount the solenoids with a bracket. Then, when you activate the solenoid, it will push and pull the lock rod. Take as many as you can get, for spares and future projects and friends. Gotta love freebies!
 
It has been 10 years but I previously installed alarm systems, keyless entry, and added power door locks to vehicles. I'd think you could pull all of the parts to make this work but you will likely have a hard time doing it. In the end, it might not be worth it.

To make the keypads work, you need to pull a control mechanism out which is likely under the dash. I would walk out to the car, lean down close to the dash, and start pushing the unlock button. The control mechanism will have multiple relays inside which you will hear click. Once you get a general idea of the location, it is easier to determine the exact box by placing your hand on it. You can feel the relays functioning inside. Once you find it, see how many wires are coming out.

I'd imagine the box would control the flashing of the parking lights, the honking of the horn, locking of the doors when in gear or at a certain RPM, and possibly more. The wires would likely enter various harnesses and be difficult to track down completely. If you had a wiring diagram for the vehicle, you could cut the wires and work on just hooking it back together later. If not, you might be able to do the same with a large amount of testing to determine the function of each wire before removing the unit.

The door lock motors could be used without the rest of the system. A Ford is normally a three wire negative system meaning the door locking and unlocking is controled by the grounding of a wire. It would be best to test this before removing the motors as I'm relying on my experience from years back. The motors would take some creativity to mount and a little more to find a sturdy way to connect the door lock linkage to the motor in a way that it would not come lose over time.

Again, I think it is possible. You could have a little work ahead of you if you want to use those stock keypads.
 
I say get the solenoids but forget trying to wire the keyless entry from the Focus. It would save you a ton of headaches by buying an aftermarket keyless entry if that is something you want.

I don't recall what the door lock switches look like, but if you are planning a custom console you could retrofit the lock switches into that.
 
Alright, I couldn't locate the schematic that I did, and I didn't feel like re inventing it, so I located this schematic. It should work fine, once you determine if you have 3 wire or 5 wire solenoids. It's really a piece of cake to do this, just a little timely. The relays are just standard relays you can scavenge a ton in just about any car in the yard, they even have the same pin numbers, or you can buy them at any auto parts store!

Oh, and one more simple one
