Citroen Relay Unknown Wires

[Adamhratcliffe]

Hello,

I am new here and have just purchased a Citroen Relay over a long distance. She turned up today with a few issues so I am looking to resolve.

Does anyone know what this is:

It is in the top right of the windscreen.

There is a 4 pin connector under the drivers dash which doesn't seem to be connected to anything - any idea what it might be from?

A lot of Citroen vans had a dealer fit smart nav system fitted made by traffic master. The screen was mounted on the dash just by the base of the A pillar. Maybe been removed as the system would be quite outdated now. It had a windscreen mounted GPS/GSM aerial & there was a mic mounted at the top of the A pillar.

It does have a Sat Nav mount but the seller forgot to include it... It's a 16 plate but I may rewire it for a smart phone. Additionally, the fuel leak off plug on injection 1 (nearest driver's side) has popped off whilst driving. Is this likely to be a new o ring job or more?
