Re: Bmw n54 12v pre-crank help
The thin red wire from the grey harness controls the aquamist's power up sequence. I really don't have an answer for you. I believe on of the wire on the DME response to keyless entry signal. Not too comfortable with that over night if a child walks near the car with a key.
Let me look into this a but further. Can you track down the 12V supply to the LP fuel pump?
