There are different models of a 703 control box, If it is the one for that engine then it should have a 10 pin harness that would plug direct to engine harness( 10 pin harness is for power trim and tilt models, 7 pin harness for non PT&T models)There is a short harness at control box(red,green,yellow,black wire)to wire up gauges
