do you still have the dx cluster? If you do see if it works properly. It sounds like a short to me, you might have to trace it back through the harness. Or it could be a bad ground somewhere.

Yeah, reinstall your DX cluster and see if it clears up, it could be a bad connection between the harness and the cluster, or a problem in the cluster itself. There shouldn't be any compatibility problems with the cluster itself.

the dx cluster did it too the only difference is that the fuel guage was the fuel guage and it did work everything else though was the same and the cluster works properly it came out of my crx and there was nothing wrong with it at all

I would check the grounds, then check the harness for shorts/loose connectors (I have never seen a loose connector on a Honda unless the plug is broken) or even the ecu could be bad.

well i think ive figured it out and im pretty sure that its the main ground and the fuse box ground they are both way too small and they are both hooked up pretty wierd so im going to change them out for bigger wire and relocate them and hook it all up right loli will let yall know how it goes when im done =)
