The only item I can remember from my old E39 with a + on top was the battery
connection point for the positive cable of a battery charger. The + was a
hinged cover that revealed the metal terminal. Any help?
I know what you mean, but it's not that. The thing I'm asking about is all
black plastic, with a built in electrical socket. The plunger part is about
10mm or 3/8" diameter.
The connecting plug has 2 thin wires. One purple and green wire, the other
brown, that disappear into the main harness.
You are right. It is (supposed to be) the hood switch.
I finally found it in the Bentley manual.
I'll have to check the clearance again, because my original check showed it
wasn't touching the hood, and there wasn't a mark on the hood to show that
it ever had been touching.
