Make sure that the stolen gauge is off a 91 Civic, so that you can just plug and play.

 

it is, thats exactly what i did with actually two of them and only the mph work, but thats mechanical, still no luck

 

I havea 99 Civic, my ECU has the same thing. I think on mine that connector is used for diagnostics, but I would double check in a manual for your 91. Go to a pick and pull yard, chances are you will find a a bunch of Honda's to choose from. At least they didn't steal the whole thing...
