Everything essentially just pulls off. But it may help to actually reach up from under the dash to get the speedo cable off. Actually I found it easiest to pull most of the connections this way.

That black thing on the back of the speedo is a tamper proof device. I guess with most cars you'd be putting in a lower mileage speedo unit. You do want to break it off. The (greasy) cable then pulls off. If you were a dealer you could probably get a replacement device (different color tho so one could tell it's a replacement speedo).

I just replaced my speedo, as it's cheaper to pull the right one from a junkyard than to pay someone to fix it (hell, even the brickboarder selling the gears wanted $25). The original one died before I got the car at 42,000 miles or so. The guy selling it figured about 120k miles (yeah, right), the replacement said 144k, so I say good enough :)

All of the connections are fairly self evident, altho I did end up with a few leftover ones, and I'm unsure why. But hey it all works. If you've got a tach, there's only one connection on the bottom.
