Hi I am struggling like mad to figure this out I'm replacing the coil harness on my 225 with the ECS tuning one. There's 3 brown wires I cannot figure where they go for the life of me( fat, medium, and skinny). I have some pictures to show what my struggle is. I'm trying to figure out where to put the 3 brown wires in the middle row of the ECS plug.

I saw a guy Doooglaaas said he made it work but I can't figure it out. Please help!

I don't know the ECS harness.
Without knowing what or where you've cut, I can't say what those wires are, or where they should go.

Brown is ground in the OEM spec. No idea if the ECS harness uses any standard.

Looking at the ignition EWD in the back of the Bentley. This is what's running to the coils.

1- coil power
2- signal ground (brown)
3- signal
4- coil ground (brown/yellow striped).

There's also the noise suppressor line.

Good luck.
