luk, my solenoids did not come with pigtails, so I am unsure which are the 'brown' ones you mentioned. Could you please take the harness off the solenoids themselves and indicate which pins are the 'brown' wires you mentioned? Basically, you can say that the knock sensor like solenoid clip has 3 guides on it, the left, the right, and the top. Looking at the solenoid with the top pointing up, the right pin is the 'brown' wire, and indicate the same for the other pigtail stating that the push button is considered the 'top'. Know what I mean?
Here's a picture to help what I mean:
