Hey guys I found this beautifull 03 sir cluster and I have a 99 dx, I was wondering if its possible to make that swap and what do I have to do to make it work properly

It's not a direct fit nor is it plug n' play. It's probably possible, but you will need to study wiring schematics to figure out which wires to splice together and you will then need to fab up a way to mount the cluster, and then finally to fab up a fiberglass or plastic bezel.

Basically, more trouble than it's worth. Check out the Si cluster from a USDM 99-00 Si, or an SiR cluster from a Canadian 99-00 SiR. You may like it, and it will bolt up directly (and I think it will even be plug n' play).
