Hey guys I've seen some threads on here about doing the swap but my question is for the interior wire harness would i be able to just cut and splice the harness past the front doors (the part under the side trim) ??? or do i just need to swap the entire harness?

Your questions might make perfect sense to others, but I wanted to post and let you know that I do not understand what you are doing. Adding some more detail about what you are doing might help others -help you.

Swap = what?

Swap = modifying a car with manual windows-> into a car with power windows?

Cheers!

hey sorry for the confusion I'm doing the power window conversion from (crank to power) my doors are all setup now, meaning they have the components for the power windows and power locks and the doors are also have their appropriate wires. My next step is for the interior wire harness, which is that twist and lock connector where the door hinge is, if i get the one that came with the power windows could i cut that harness where the wires start going to the rear of the car and remove the same portion from my car then splice the wires into my harness where they go to the rear of the car? wouldn't the wires that go to the rear be the same on every car? so i could just color match the wires going to the back?.......... does that make sense? if not i can try and upload some pics of where on the harness I'm talking about. thanks for any help

I have never done what you are doing, so can't help much.

Let me re-word your question;

Were all Foci in 2002 manufactured "pre-wired" for power windows/locks inside the car -and- the only difference in these cars was NO wiring inside the doors only?

Answer = I do not know.

Could I take the doors off a car with no power windows/locks and install new doors that have power windows/locks and expect the power windows/locks to work?

Answer = I do not know.

--------------------------------------------------------

You will need a set of eyeballs, a multimeter, and a wire diagram to find out if your car is pre-wired or not. HERE is the wire diagram.

... the answer is NO to both
If you are sure the answer is NO to both questions... you have lots of new wiring to add into the cabin of your car. So, you can not (successfully) do what you first suggested because the car cabin is not pre-wired. Getting that piece of the harness (the door rubber boot Male and Female connectors with wires) off of a junkyard car that has power windows/locks would be a good first step and lots of help.

Good luck.

Best I can figure, it sounds like you're asking if you could cut out JUST the twist lock connector pigtail & splice it into your car's wiring harness to make it work.

Doubt that would be possible for more than minimal function, as most of the wires needed wouldn't be present in the harness. (i.e. - you might find a useful power lead to tap into for example, but not the full set of communicating wires)

Hey! Cool, look who showed up!

.. cut out JUST the twist lock connector pigtail & splice it into your car's wiring harness to make it work.
BTW the twist lock connector (male plug) is on the door side & is part of the door.

The real question here (for me) is what power window/lock wiring is pre-existing inside a car that came without power windows?

I am actually right in the middle of this swap right now. I have pulled out all the manual stuff, window, mirror. it had power locks. If you have manual locks make sure they are actually manual by taking the door skin off and checking the actual locking mechanism if there is a wire going to it then you do have power locks but you need to replace fuse 63. and where is fuse 63 you ask? Its on the back of the fuse box and you will need to pull it off to get to the back. its not fun but it is the easiest way. all the wiring for power windows and mirrors is already there you just need the "in door wiring". I will do a write up when I am done my swap best way to do it is have donor doors to do the swap.

I just did a door swap.

You will need the wiring that comes from the car into the door. If you didn't get the option, your car doesn't have the wiring. The interior parts are easy enough to swap though.

Aftermarket power window kits usually keep the spline part. You slide this plastic over and thats driven by an electric motor i think.

To be honest, doing it the OEM way is the way to go, and I'm talking from experience. My old 2dr Escort had crank windows, and I used OEM 2dr parts (which is extremely rare).

It isn't that hard to do. It's really straight forward and usually the wires are already there.
