Regarding the MS grounds, there is only one ground plane on the MS.

If so, there should be a separate wire from this ground plane, to the engine bay, to which all sensor grounds are returned. However, this won't work for sensors which are grounded through their body. Any sensors grounded through their body should NOT be connected to the above wire.

A second, thick wire should go from the ground plane, to the engine, to act as power ground.

Any other grounding scheme may not work.
