T6.1 Wiring diagrams, 91 & 94 pin ECU plugs

[Mooeee]

Stripped out an Engine bay wiring loom, not the engine wiring loom, but the loom that actually connects to other modules and sensors in the engine bay and onto the interior wiring looms, removed from a damaged 2023 T6.1, when looking at the ECU plug it has 91 pins, my confusion is that all the T6.1 wiring diagrams are showing the ECU plug as having 94 pins, are there any diagrams available for T6.1's that are showing the wiring connections for a 91 pin plug?

Another thought that there maybe different variations of ECU's that are fitted to various Transporter models?

What makes it even more confusing is that the diagrams show wires connected to pins 92, 93, & 94.



Any help would be appreciated.

Thanks

Unfortunately the wiring diagrams are not produced like that, they are done by system/function and not loom/location so pinouts of particular connectors tend to be spread across different diagrams

Perhaps if you could post some more details and some photos etc of what you have/what you are trying to achieve/what documents you are looking at etc etc then we may be able to take it further ?

Thanks for the reply Pauly, I do appreciate that and understand the wiring diagrams are spread across different systems and over many pages, that is not the problem I can read all the wiring diagrams. I was checking the pinouts from some of the plugs that have been broken on the engine bay loom that I have stripped out of a T6.1, the wires going back to the ECU plug do not correspond to the wiring drawings, down to the fact that the plug on the engine bay loom has a Bosch 91 pin plug and all the wiring drawings on here show the ECU plug with 94 pinouts

T6.1 engines DNAA, DNAB, DNAC, DMZA have 91-pin plug. The others (CXEC/CXFA/CXGD/CXGE/CXHA/CXHC) have 94-pin plug.
Yes, there are wiring diagrams for those, too. Unfortunately not in Forum depository, yet.

Thanks for the replies, would be grateful if these could be uploaded or a file sent personally with the diagrams. I'll be honest and say that I don't know what engine the vehicle had, only spoke with the guy breaking it on the phone about the wiring, has the 91 pin ECU plug and if that is the 4 engine codes DNAA, DNAB, DNAC, DMZA 89, 90, 91 that had a 91 pin ECU plug then that would be great. It is a 2023 Transporter.

This is just a long term project that I started and not sure how it will play out.

Attached is a couple of pictures that shows what was left when I went to remove the dash, rear compartment and the engine bay wiring looms from it, all bar the actual engine loom that obviously went when the complete engine was removed.





Only things left last time I was over there was, the driver and passenger doors, the N/S sliding door which are all unmarked, and the rear & front suspension, Oh and the dash heater complete.

No Vin Number or Registration on it, Colour Ascot Grey.

Really appreciate your help.
