electrical connectors underneath seats

[Timbers]

Hello, I've recently replaced the standard single and double seat on a T6 2015 with T6 Caravelle front seats. But when I've come to plug the electrics back in I have the following problem..
The connector plugs on the seats don't mate with those on the van. Which plugs should I replace? Secondly, there are a number of plugs on the van, so how can I identity which I need to plug in?
The seats are manual, and I do not believe they are heated. So I guess this plug is purely for seat belt warning.

pic 1 & 2 - show the seat plugs
pic 3 - plugs and wiring from passenger side
pic 4 - plugs and wiring from drivers including a smaller plug I'm holding, no idea!

I'd be grateful for any advice on this or indeed which manual I'd be best off buying.

This is my first post on the Forum, I got my van earlier this year and I'm in the early stages of converting it. Cheers, Tim

Which plugs were actually connected to the seat prior to removal ?

 

[Timbers]

Unfortunately I didn't make a note of that. I only have one plug coming from each seat so the rest of them (on the van) are unknown and not needed!?

 

[Niknak]

It will have a generic loom so the seats only have the one plug ?

Looks like it’s just the seat belt buckle warning plug, if they are not the same plug you could just connect the wires with a different connector , the others from the passanger side are for extras, did your original passanger seat have no connections? Unless your new seats have heated or anything else about them you want to use them don’t worry about connecting ( are any of them air bagged if so be careful)

Hi Niknak, thanks for getting back to me.
the seats are not airbagged, electric or heated, so they can only be seatbelt warning plugs. I'm thinking I will get a couple of corresponding plugs to fit at the seat end and then just try them all out,
on the 'loom' side and hopefully this wont blow a fuse.
As you say, its a generic loom so the rest of these plugs wont be relevant, but it would be nice to know what they are for.

The coloured connectors should all be plugged into each other, they are coupling points on the main van wiring harness and nothing to do with the seats (other than the fact they hide underneath them)

Cheers Pauly, that simplifies things.

As for the leads attached to the seats, I'm guessing they are for the seatbelt pretensioner circuit? Or perhaps the eats are hated but I dont think so. Either I need to somehow wire them in!

Given where you are upto so far I would avoid wiring heated seats yourself if they do turn out to be heated.......

politely put I couldn’t agree more, I’m just glad everything still seems to be working. Cheers

Pic 4 is the seat contact (for the safety belt light) I believe. If there was an airbag in the seat there's a second connector which is yellow.

To test what the seat one does, maybe put 12v on it, and test with a multimeter what happens if you sit on it. Probably goes with the connector of pic 4

Although, could your connector be the t4av in the next picture? ("Steckverbindung 4fach, scharz, unter den Beifahrersitz") The G60 is the temp sensor of the seat, with a brown, a white/black and a blue wire coming out...

All other connectors, as mentioned above, they're just there because they're there, nothing to do with seat, just plug them in.

Hi Sippe,
The seats are heated afterall which explains the plugs coming from the seats.
I will lift the drivers seat and have a proper rummage about to find anything to fit the ‘safety belt light’ with the corresponding plug in pic4.
And as you say, the rest of them just plug together as before.
Thanks for your help, cheers

Hi Timbers

The safety belt plug is clipped on the bottomside of the top of the base I seem to remember, somewhere in the back corner (don't know if this is clear...). This was for a LHD, but it will be similar for RHD as the cable is not longer than that.

If you have a swivel, easiest is to turn the seat slightly outwards, that way you can just reach with your arm between seat and swivel. Without swivel you can reach from underneath.

Good luck!

btw it's a good season to feel the difference between heated and not

You're not wrong, it would be great to get them working - though looking into its quite an involved process to have them wired in with a new temperature control panel and to pay professionals is well over £600 so perhaps I will just put an extra jumper on for now..
