To make sure I understand correctly you stating to cut and intercept one of the lines (either grey or brown since polarity is not important) going to the boost solenoid. The white HFS-4 wire of the grey ECU connector will go to the controller and the brown HFS-4 wire of the grey ECU connector will go towards the boost solenoid as displayed in example #2 of the HFS-4 manual. Is this correct?

Without knowing the polarity of those wire from the e-boost module, I can only give you a general guide.

I suggest putting the HFS4's white wire to the eboost side and brown wire to the solenoid valve side. The diagram is not very easy to read. the text are too small to make sense.
