Anyone know what this is supposed to do?

I was looking at my 1hdt manifold to plan out my egt gauge install and looked at a ground wire on my valve cover and noticed the ground going to my turbo. I dug around and found this sort or wrapped around the turbo, and it has a male/female plug that goes to a ground.

What is it?

Tried googling the "EC Spark for Diesels" and got nothing.

Probably a grounding kit installed and that band looks like a banana warmer or bracelet

doesn't make sense perhaps for cast iron to aluminum to prevent bi-metallic corrosion between the 2 metals

I don't think it was doing much of anything anymore. The wire going into it pulled right out and the end it came out of us a bit cooked.
Found this link for one that sold but I can't read Japanese and it doesn't translate. Shunwa electronics made it but can't find them either.
