I bought an HFS-3 v3.1 system second hand from a guy with Porsche. He never installed the system so it's still new in the box. I've been looking over the manual and it seem there is a soldering modification that needs to be done in order for the system to work properly on my car. Can anyone confirm if this is correct on the diagram?

I have checked my circuit board and it is not soldered between link 1 & 2 for the single jet application.
