V1 Ground between the ECM and BCM?

[AZmoto]

I'm finishing up the wiring harness and have a ground wire coming of the BCM that is cut and knotted. Did this have a special purpose? I can't remember at this point.

Also I noticed that there does not seem to be a ground connecting the ECM and BCM. Is there supposed to be?

If that wire is not coming from a copper ground lug then I would make sure it gets grounded.

About 2 minutes into Video 11, Lonny checks the grounds to all the components. Check those as well as any custom features to make sure you are not missing anything.
