The three, second from the left are the ones that mount to the top of the cluster and hold the wiring harness (if I'm remembering this right, it's been a while since I was working on that.) Long one on the right looks like the ones welded on the underside of the cowl. The others ??? There should be a diagram showing those in the assembly manual.
