Short answer, Yes if both engines are Rotax 2 strokes. If the donor engine is non Rotax check the rotation of the donor engine.

I’m not an expert, but I believe that it should be to the airframe. Every drawing that I have seen shows a common ground (airframe?) throughout the installation.
A couple of “However”s though….
Many installations put a separate grounding strap from the engine to the airframe (a braided strap) and then ground, at a convienant place, the devices fed by the system.
If the loads off the KW are not too demanding and depending on how they are wired, the brown to the Neg (-) on the KW would be “ok”, not ideal, but “ok”.
As Beauford would say.... "Worth what you paid for it!" (Who by the way, uses a KW and an EIS.)

The output (DC) of the Key West would tie into whatever you have that requires the 12V DC. The brown (ground) going to the negative side of the output of the KW may have been someone's way of getting the engine ground to whatever is being fed by the KW.
