CHASSIS: CLASSIC DATSUN

• Classic Datsun including 510, 240z, 260z, 280zx, Roadster
  
• Our Universal PRO harnesses are a perfect solution for the engine, and can come with an optional self-contained pre-wired fuse/relay block for ignition, cooling fans and fuel pump.   If you plan on using your own relays and a switch panel, you do not need the fuse block.
• You just have to hook up start signal, fuel pump wires and a few other wires for tach and speedo, alternator warning light etc.
• Speedo and / or tach may need to have the signal adjusted using a frequency modulator (see Options to the right). You may have to run aftermarket gauges. Not compatible with mechanical cable driven speedometers.
