k5 speedo drive same as 2000

Hi guys. As some know I'm putting my minitwin race bike back on the road.
<----That one, oh yeah, she's sweeeet.

I just need a speedo drive now. I've lost a few on ebay as the bidding went sky high.
My question is:
Is the k5 speedo drive the same as the 2000 ? Are they all the same ?
And where does it plug in ??? I don't seem to have any spare plugs on the loom. The previous owner modified the loom for racing so I'm unsure what is missing. if anything is at all. This is my first sv so I'm in the dark a bit.

My only other option is a cycle computer but I'd really like the original speedo working. Cheers guys.

p.s. check out pic of last nights shed based wiring hell.
Yes my shed is carpeted lol.

oops !
