I'd say the red wire, grey wire, and the square sensor, are not Land Rover. Possibly an old telephone installation, or a tracking device. The square sensor may possibly be a GPS receiver. The white connector may be Land Rover, prepared for a seat occupancy system that was not installed in your car.
Are there any other signs of equipment having been fitted or removed? Perhaps on the side cheeks of the centre console or on the dashboard.
Mainly I think you are on your own tracing these, but I'm not sure that even when you find the other ends that you will find a cure to the Fuse 10 issue.
PS, It would help if you put your location in your profile. I've gone to the trouble of looking at your previous posts, which suggest you are in Namibia. In this case it would also be useful to indicate which market your car came from. It might help get appropriate answers to current or future questions. I don't see how it can be negative for your location to say 'German car now in Namibia', or whatever is accurate.
