What is this part on a Euro 1991 190e 1.8 RHD?
Opened up the passenger carpet while doing an amp install and found this red connector embedded into a removable plate in the footwell area.
It seems to come from the side but goes nowhere.When the plate is removed, there are no wires coming out from the connector.Looks like a port of some kind.
On the connector (it's a she - female), it has 4 pins labelled 1 to 4.
Only pin 1 and pin 4 (damn, i forgot) have metal contacts in them.
Both pin 1 and pin 4 measure 2.9 volts to ground with a warm engine.
Any idea what it is?
