Not really, you do have to pull the speedo/cluster out a bit to get your hadn behind it.. then you feel around, find the cable head.. and squeeze it.. The speedo will pull away.. Once you have done it once, it is easy..
Heck, while your in there.. why not short the 20 ohm resister in there and change your oil sending unit to get a real oil pressure gauge (search for "fake oil pressure" for more info)
