I bought this GNX style dash a few months back and It didn't come with any sending units. Well my car is almost done up at Dynotech, but they're stumped on what sending unit and speedometer cable is used. Everything else is routed through the stock harness and all the other sending units were installed new. But they can't move on unless we find out what the right Speedometer sending unit and cable are. Any help is greatly appreciated.
