I got a 89 civic ef std with a 89 si cluster.. the previous owner apparently did some horrible ground work in the dash harness and it made a wire catch flame. So my buddy gave me a 91 fuse box and dash harness since a fuse melted and wire melted other wires in old harness. Does anyone know the wiring diagram ill need to follow to make 91 harness workn with a 89 si cluster. Of course tach isn't workin, gauge lights and oil light and check engine light are coming on only when headlights are turned on. Fuel and heat gauge ade also not workin. Neither is the heater control lights.
