New to site... Need help jdm integra type R cluster wiring

I bought a JDM type R guage cluster thinking it would be plug and play in my 97 integra LS. When I plug it up everything works fine except the gas guage pegs out and stays there. I'm sure i just need to change some wires but I don't have clue which ones. Any light would be apriciated in this dark tunnel.

Thanks
