The first picture is a file photo of a similar bonding wire for the 1988. I don't think this originally came on the engine but was added later. I think it bonded the steering assembly to the midsection , but I'm not sure were it was mounted.
The second picture is a part I removed from a 1991 engine I salvaged for parts. I'm not sure where it was mounted, or if it was on the engine or the hydraulic steering.
I could not find either part in the exploded parts diagrams for either engine.
