wires have been cut, but all are still there. need a basic diagram with color codes and where they go. Please help. I believe there's a tilt, fuel, tach, and speedo gauge..... thank you........Pete
There are several schematics on here, look in the sticky's.
Black is ground, purple is ignition (12v when engine switch is on), pink is fuel sender, grey is tach sender, blue is gauge lights (usually from running lights). Trim is dependent on engine make.
