how do you hook this up?

Does anyone know how to hook up a ef9 jdm sir cluster into a 91 civic dx ? I got a cluster and I want it in but it's giving me alot of problems. If anyone has a website or any info on how to hook this up please help! thanks

damn I forgot to add also ... do I need anything for the spedometer??? I heard I needed a speed sensor or something can anyone explain that?
