Are these details sufficient?
Do you also need the part number from 1Z?
If I were to move the fuse box, then the wiring harness in the vehicle, the instrument cluster, and the WFS black box with its transponder ring and transponder would also need to be moved. Or?
Does the engine wiring harness also need to be replaced?

I would leave it as it is and get a WFS box from a Golf 3.

Otherwise, get the wiring diagrams; it will cost you €100, but it's definitely not a bad investment. Maybe you can find them cheaper somewhere else.
Alternatively, you could take it to a tuner and have them disable the WFS (but it seems like a pointless and expensive solution, and if someone steals your car, you'll still be stuck with it and feel foolish).

The correct WFS control unit is 1H0 953 257 B, which you can find starting at 30 EUR at RAR. The WFS login can either be obtained from the dealer, read from the WFS control unit, or copied from the key fob of the donor vehicle.

Okay, so I took the WFS module from the donor car, which came with the transponder and transponder ring. Is there a way to connect this to the older wiring harness? And how does that affect the speedometer? Does the anti-theft device also need that?
If I buy one of those boxes, can I simply connect the wires according to a diagram instead of connecting them to the original components?

Then you just need to adjust everything to fit, and it should work.

No, in newer models, the instrument clusters are part of the WFS (Vehicle Function System) network because the WFS control unit is integrated into the instrument cluster. However, this is not a problem if you are using a separate WFS module.

You don't need to buy a WFS box if you already have one.

The problem with all your statements is that you always mention the important things only after people have already thought a step further... icon_sad.gif

I mentioned above that I have a box, and I don't know how to connect it to the wiring harness.
The car has an extra box located under the light switch. A cable runs from this box to the ring on the ignition switch. From the fuse box, cables run to the instrument cluster, etc.
"I'm not sure how to connect it because the wiring harness for the instrument cluster is a bit different. The instrument cluster also has a digital signal, while the one from the 1Z has a speedometer cable. I want to avoid having to rewire the entire fuse box and wiring harness." I'm not sure if all the plugs will fit.
If there's no other way, I guess I'll just have to do it.
Regards, Stuffy.

So, to be more specific...

Does the vehicle already have a WFS box? If so, what is the part number?
Did you get a WFS box with the new engine? If so, what is the part number?

Okay, so my car didn't have a WFS. But the new engine does. I swapped the engine (AFN) into the 1Z vehicle. The engine wiring harness is still the old one. I can give you the numbers tomorrow. I don't have it readily available right now.
The instrument cluster is still from the 1Z model. However, I still have all the related parts. Okay, so we have a WFS box with a transponder, transponder ring, instrument cluster, and wiring harness...

As I mentioned above, in your case, the combination instrument is NOT part of the WFS!

There's a cable running up into the instrument cluster. Or is that just an advertisement?
Where do the other cables from the WFS need to be connected? Do they fit the old wiring harness?

You should really just get yourself a wiring diagram. icon_cool.gif

The wire running through T28/13 is terminal 15.

What kind of WFS box is this? Is it a 10-pin connector? icon_smile.gif

That is not a G3. This is a Passat 35i.
Okay, so it's the WFS number 1HO 953 257 BB from Siemens.
Today, I tried to locate the wiring harness leading to the control unit, but unfortunately, I was unsuccessful. Which pin(s) is the WFS now connected to on the STG?

It's all the same mustard.

Okay, so, similar to the part number I posted above, the WFS-I is also compatible with the new engine.

Do you have a wiring diagram, or are you searching "blindly"?

Right now, I'm just searching blindly.
Unfortunately, I don't know anyone at VW who could copy a wiring diagram for me.
