Wiring check for MFSW on T6.1. I have had to replace wheel as the OE had been butchered for disabled controls.

[Jvcarrier]

Wires into the clockspring are Wires out of the clockspring to yellow socket are
Pin 1 Brown/Blue banding Pin 1 Brown
Pin 2 Black /yellow trace Pin 2 Grey
Pin 3 Purple/White Pin 3 Purple/white
Pin 4 Red?yellow Pin 4 White

(Ignoring air bag connections)
Wires to MF switches

1 Brown
2 White
3 Purple /White
4 Empty
5 Empty
6 Grey

Does this look right and how do I get the horn to work? The wires into the Clockspring are the ones I had to re wire so I am concerned I might have misplaced a couple of them.

Any help appreciated.

Regards

John

Thanks for the current flow diagrams. Sorted out the missing blue/ white one.

Next issue is that the under bonnet electrics do not turn off, whilst engine turns off some engine functions stay live and pull quite a lot of current.
Ignition is off and all seems usual from the inside. I area is a solenoid on the intercooler output.

Any ideas of what to check to shut it all functions down would be great.

Thats a slightly vague question, perhaps some photos and a bit more info of the issue and we may be able to offer some advice

Thanks Pauly,
The dome shape at the bottom of the picture [at the end of the hose leading out of the intercooler] is whining constantly, in addition there are other electrical noises from the engine compartment. This is whenever the battery is connected regardless of the key position. Plus I can disconnect all of the terminals from the key and it does not terminate these engine circuits. The only way I can stop the engines “activity” is by disconnecting the battery. The engine starts on and off by the key as one would expect.

I wonder if it could be a relay that should energise as part of the start process that has failed when closed, or given it was a modified van for a wheelchair user it possibly had an unusual start procedures.

I presume when the transporter are switched of all the engine electronics are shut down within a shortish period.
I think my next step would be to get an ammeter to find which wires remain powered up.
I am having trouble finding electrical diagrams for the van which Is a late 2023 with a model year of 2024.
Any thoughts appreciated.

Regards

John
