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.
