Tach Display

Hi,

Just bought a Yamaha 70 Autolube from approx 1994 and was given a Tach display and a 703 control unit with the engine. I have the 703 and engine working fine but don't know where the display harness multi plugs go! Can anyone help?

One harness connects gauge to engine for trim sender and oil level signal, the other harness(one with inline fuse in it) connects gauge to 703 control box for power and tach signal.

Thanks for the advice. I can't find anywhere on the outboard to plug in the harness. Don't know if this guage goes with the motor. Also there are four wires and no multi plug from the remote. Sorry I sound a bit thick but I'm new to all this!!

The trim/oil harness harness connects to the two off white colored square connectors on engine that matches trim/oil harness. The gauge harness connects matching yellow, green, black wires on 703 control box.
