Help with HFS-4 v3 setup on BMW Z4 35i (E89 N54)

[Ramjet]

Hi,

I need some advice on the wiring of the HFS-4 to my BMW Z4 35i. I have used the 335i N54 version 3 wiring diagram downloaded from the forum. My questions are:
1. Do I cut the white DMU ?7? wire for "failsafe wastegate valve" as shown in this diagram (circled orange in attached picture)? I have installed the wires exactly as shown in this diagram.

2. The default jumper setup shown in the version 3 install manual (supplied with my HFS-4), and the default jumper settings in the BMW 335i wiring diagram (from the Aquamist forum) show different default jumpers. I note however that although the 335i wiring instructions (from the forum) states it is for version 3 boards, the picture of the board in the 335i wiring diagram does not show the ?version 3? board as supplied. I assume I use the version 3 board default settings from the manual, but change ?CEL? to ?DR1? as per the 335i wiring diagram?

Any advice you can give to clarify would help a lot!

Thanks!
