I have one pulled apart I'll double check
I have seen this is most OEM looms hence why I follow that route for my grounds but add heavier gauge up to the point where all the other grounds junction from and between the groups. Basically its just the OEM method with better material budget.
As for what VL said about running completely isolated one for the ignition I see the point and agree but I have never done it as I have never built a loom that uses grounded coils as they have all been the V6 style bi-polar coils and DFI modules self ground via the bracket so I don't need to do anything there.
For my next loom it will run LS coils so I will do something different there but that's some time away to even think about it at this stage.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
