Instrument Cluster compatibility

[steelerfan7111]

I have a 91 Honda Accord,and need to replace my intsrument cluster. I assumed the 91 cluster was interchangeable with all 90-93. Well i got another cluster from these years off ebay that was for an automatic,like mine is,and has the NS under the Unleaded fuel lettering,like mine does. But when trying to install it,i noticed the front left harness plug and the top harness plug are slightly differnt and wont fit into the cluster from ebay. Is there something specific I need to look for in another cluster ,to insure compatibility with my 91's wiring? Any help is appreciatted. Thanks.
