Hi, I’m looking to swap out my double for a single seat. The wiring in the double appears to be just two wires that split off to the two seatbelt stalks and two pressure sensors on the seat bases. I’ve read that fitting a 3.3ohm resistor to the seatbelt plugs will stop any faults showing. Does anyone know if I can just fit one resistor to the red plug that splits the loom in the seat base? The single seats don’t have any wiring to the stalks or seat sensors. Thanks

Pre 2025 models have just the simple circuit for the passengers seat(s) as far as I am aware. Here is the diagram. As you see the note '2' indicates the extra wiring when a double seat is fitted so no reason why it cannot be removed. FYI the brown wire simply goes to a chassis ground somewhere in the vehicle loom.
I've got single seats from new but have fitted a passengers double in the rear and connected the belt warning from that in parallel with the original passengers one and it all works as it should.
From 2025 this is very different!! I'm working on producing an extended loom for those fitting a double swivel into a 2025 onwards van. Prototype is in service OK and a fully working 'plug & play' version should be available within a couple of weeks.

You shouldn't need any components added the circuit as in the diagram I posted is simple.
I think the buckle contacts are shown incorrectly, My take on it is that they are 'made' when the belt is not buckled thus when a weight is put on the seat the sensor conducts electricity and when the belt is buckled the circuit is broken again. Current flowing = warning on, circuit broken = no warning.
I have a 2025 TGE with single passenger seat , took it out and fitted a standard double seat for occasional use,I intend to swop between the two seats, problem is I have brought a airbag warning light on dash, is this an issue with anything ? And will it go out when I reconnect the single seat ? Do any double seats have sensors fitted like the single seat I have ?
Yes! 2025 onwards models have all four sensors / contacts wired out from a double seat individually, i.e. eight individual wires.
No the warning won't go without re-setting it with VCDS or similar.
Someone may have discovered how to bypass the alarm system but as far as I know if the Red 17way connector is disconnected you will have an airbag warning.
I am in the process of making extension looms for the double seat when used on a swivel so that everything remains working as it should when the seat is rotated. This will have all 17 wires connected via Red 17way male & female plugs / sockets so that it is a true extension loom useable for all versions of the double seat.
Watch this space for the availability of these looms later in the year.

Hi all - anyone know if it’s possible to disconnect the dredded red connector after disconnecting the battery ?
Will it come back without the error if re-connected before power is restored ?
(I want to remove the seat to aid working on the electrical system)
It’s a facelift 2025 model TGE.
Many thanks.

Simple answer, if the ignition is switched on with the plug out you will have an airbag alarm on the dash. You 'should' get away with removing the plug after the battery has been disconnected if the plug is replaced before reconnection. Note that I said 'should'.
If the airbag warning comes up you will need to have it reset with some version of diagnostics kit.
If you (or other readers) are intending fitting a swivel under the double seat the loom needs to be longer. I am in an advances state in the production of a plug & play loom extender but it's not going to be available until at least late November.

That was quick, cheers Rod_vw.
I think I have enough access to the relay box without removing the seat or unplugging it, so happy days
On another note, anyone know the blade / spade terminal type for inserting into the factory relay modules + standard fuse holders under the passenger seat !?
(I have some relay inserts and a 12 way fuse holder coming from MAN.. I already have standard 5 blade relays and standard fuses with the 6.3mm blades)
Many thanks.

Call upon the knowledge of @Pauly , admin of this forum he is a fountain of knowledge on the subject. I expect he will be along in a while having seen his name taken in vain here.That was quick, cheers Rod_vw.

Can you post a couple pics of what you are trying to populateThat was quick, cheers Rod_vw.

I can point in the direction of most crimps/terminals just one size of 6mm i have never been able to find

Hi Pauly, thanks for the reply - yes of course - please see enclosed.
I want to put standard relays in five of the unused spaces. I have OEM carries coming for that.
I want to put fuses for the loads in the unpopulated space to the right. I have the OEM fuse carrier coming for that too.
I have heard the fuse carrier takes 4.8mm "standard power timer terminals", not sure if thats correct. example here:
www.3waycomponents.co.uk
I have no idea what the relay carries require. I am running standard relays with 6.3mm blades, 5 pin.
Any thoughts most welcome !
Many thanks.
Ps. In case its relevant - all these circuits will be powered from the leisure battery, i’m just trying to be effiecnt with space…. I don't need to change any of the factory wiring at all.
