Did you ever figure out how to fit the touran plug in to the 2012 caddy? Mine is 2011 and got the same issue. Picked up some door cards and regulators today but the plugs are different. Not sure if there's any easy to way sort this or might just be better buying the retro fit kits.

I got my Caddy windows sorted.

So the issue is the new Caddy door plug is different to Touran ones. The way I solved it with a bit of help from someone else that had done it, was to not even bother changing the window regulators or wiring loom at all. This also speeds up the job quite a lot.
I took the window motor off the Touran regulator and removed the winder on the original one. The fitment is the same and after drilling the rivets off the original regulator, the electric window motor and door control bolts on no problem to the original regulator.

2nd part is running a live wire in from the car. I used a wire to run from the fuse board, got pins and attached them to the end of the live wire so it was done as well as I could, to get to the other window I just used a splice clip to run the other wire to the other door.
I just pushed this wire in to both plugs between the body and the door, using the pins I'd attached to the wires. You can buy kit's of these pins from Radioworld or off Ebay that fit the plugs. If you can't be bothered to make your own wire and attach the metal pins you can buy pre made wire kits off Ebay.
I did the same to run the live in to the door and attached this to the window control module.
I used a 15amp fuse in the board. Not sure what fuse it should have but had no issues with it so far.

This should get both windows working but the door card I got from the Touran was from a 5 door car, i.e. has 4 window switches and a 10pin plug.
I decided to buy a 2 switch trim and 2 window switch (again both off ebay) as the trim and switches were pretty worn anyway.

The problem now was the driver side plug is a 10pin plug and the new one is only 4 pins.
I found a pdf document for a Golf workshop manual and it showed the 10pin plug wire info and a 4pin for a passenger side. From this I worked out fairly easily the wires that needed to be swapped.
The hard bit was getting the pins out of the 10pin plug but I worked that out.

I then took the 10pin plug and put it in the vice and cut it to 4 pin in a line and left one part sticking out to fit the shape of the new window switch, done carefully with a file and saw you can get it to fit really snug. I presume you could find one at a scrap yard but the the only thing I could see online was buying the full wiring loom, which I didn't really want to do.

Now it was just a case of sliding the wires back in the back of the modified plug,

10pin plug
Pin 5 Red and White
Pin 6 Red and Yellow
Pin 9 Grey
Pin 10 Brown and White

These wires now need to go to the modified plug in order
Pin 1 Brown and White
Pin 2 Grey
Pin 3 Red and White
Pin 4 Red and Yellow (if the switches work the wrong window, swap pin 3 and 4)

Make sure none of the spare wires touch, cut them all back or cover them up just to make sure.

The other thing I did was since I had no electric mirrors I removed the door lock switch from my original and swapped it in to the new door card so it has no mirror stick sticking out. Just a few clips to get it out, wasn't a hard job.

Hopefully this all works for you. I found it quite hard to find any of this information on how to do this but got there eventually.

Hi mate, I'm doing an electric window conversion at the minute. What pin in the plug did you put the extra power feed? I can't find anywhere that shows which one it should go in

Hi guys I fitted my touran door cards and fitted the extra live kit, motors work beautifully, but the passenger door now doesn’t lock and the welcome light doesn’t either, Had vcds on it and there is apparently no signal to the locking mechanism, so going off that I’ve ordered a new door loom and I’ll try that, any suggestions or explanation to this issue is more than welcome,

Few details to help out
2011 caddy facelift
Touran door cards with 2006 motors but broke out of a 55 plate touran
Locking mechanism worked perfectly fine before hand
All wires seem okay at the pins on every connection
Including behind fuse board.

Any help will be much appreciated

Hi Jeff1994, welcome to the forum.
The 2006 and 2011 door control modules have a different pinout for the door lock, the signals go onto different pins.
I'm surprised your driver's side works ok.
You'll need to repin the door harness to suit the new door control module.

That has me baffled, I've never heard of the locks working properly and the internal button not. I'm thinking that's down to a faulty button.

It locks and unlocks the barn + sliding door. You can here the central locking trying to unlock the front doors, but its the lock button that doesnt lock the fronts.

Very wierd, iv get a open signal fault on the front central locking when you hit the emergency unlock button

I'll have to find your thread on the subject and remind myself, it's been a while since I've looked at this problem you are having.

Hi doc thanks for the reply, do you know which pins are which? Or could I get 05 motors pair and would that work?
I’ve been told than I need 05 ones or earlier.

I'm not in a position to look up the wiring right now, I'm fairly sure I put it in a thread in the electrical section of the forum but as a new user with just two posts you won't have access to that yet.
I don't understand why someone would tell you that you need 05 or newer door modules when yours are from 06??? There must be confusion somewhere...

Not a problem doc, whenever you get chance or I get access to that thread I’ll check it out but I spoke to a guy in fb caddy page about them for months and 2011 caddy’s with manual winders they apparently have the same plug as a 2005 or older (earlier) tourans do, so I’m thinking that is the issue the motors being off a newer (later) model touran so would be a different pinout but got the motors fairly cheap so might be worth changing the pair to an older (earlier) set.

Ah, FB facts....
There are three generations of door control modules, 2004-2009, 2009-2015 and 2015+
They all have different wiring for the door lock even though the plugs are the same.
The locks themselves are the same so it should be just a wiring swap.
I'm surprised with the amount of "Caddy Specialists" I hear about on FB, that none of them have posted up the wiring schematics to help everyone out on there.
