Re: BMW N55 electronic wastegate
It is better than I expected, you are full of surprises.
I will make up an interface board for the EWG/HFS4's grey harness. I will use the White, brown and black wire. I believe those wires are available.
I will also send you a T-Map harness so we can that too. Please pm me your address,
