this plug has been there since we purchased this 325is a year ago, car seems to run fine just wondered what this is.
comes down beside the auto tranny.
It's harnessed together with a large cable until it gets down right before the tranny,
& then there is like 2 foot hanging loose with the plug. & I cant see anthing for it to plug into.
The large cable goes on to the rear on top the tranny.Battery?
After removing the alt, I can see it originates up under the intake to somewhere. I can tell enough to see it is not going to the engine coolant sensor or the or the other temp sensor, not the vanos, or the mass air.although any of those I would notice right away, I think. well the car seems to run alright, milage is a little poor at 19mpg,
it has 2 wires (1) BROWN (1) WHITE-WITH- GREEN STRIPE.
