GTX DI battery ground cable help!!

[Lsslydogg]

Hey guys, so I bought a pretty nice 2002 GTX DI last fall with a bad engine. I had the seadoo shop rebuild it and I'm currently installing it. I found a negative battery cable in the box of parts and can not figure out exactly where it goes. It has 2 holes at one end a single hole at the other end with a rubber post cover.
I installed one negative cable to the battery and a another similar cable to the engine block, but without this cable it will not start. Where do both ends of this cable go?? thanks for any help!!

The shielded end goes to the engine block and the double hole end goes to the battery.

On the double holed end that goes to the battery like Jesse said the second hole is for a ground wire for the MPEM

Awesome! Great and thanks so much guys. I was running the MPEM ground to the battery directly, and the rear ground to block. But now I got it straightened out and she fired right up. Thanks so much
