dinkus,
Go back to the dealer where you bought the control (704?) and the digital gauges. What you need is the rigging instructions for both. I think they should have provided the instructions, but you may have to pay for them too.
Good luck,

all you need is the harness from the tach to the motor and another harness to the control box, 6y5-83553-00-00 for the tach and 64d-82553-50-00 (16.4 ft) for trim and oil level.
