I just purchased a 1995 88spl evinrude outboard. It came with the control box,wire harness, and tach. I plugged the harness from the control box to the connection under the shroud. It looks like the 3 wire harness on the tach goes to the back of the control box, is this correct? There is another 3 wire connection by the shift handle about a foot long. There is a 5 wire harness on the rear of the motor coming out of a black box that I don't know where it goes. The tilt and trim botton on the motor works, but the one on the trottle handle does not. Do I somehow have to connect the 5 wire harness on the back of the motor to the 3 wire harness on the control box, and if so what are the other 2 wires for? I hope I explained this to make sense and hope someone can help me. Also where the harness connections are made under the shroud, there is a single tan wire with no visable place to connect it to. Any help is greatly appreciated. Thanks
