Hi I have read many questions on tilt and trim problems. I have only had tilt and trim on smaller JohnyRudes They all had a connection box. I just started working on this 115 Evinrude and found that the trim motor wire aren't connected to anything.The system works fine accept I don't have any control? I read a post that leads me to think its on the back of the engine to the left of the fly wheel as you face fwd.I have found a small box with three wires two on top one going to the bottom. they seem to be the right color as far as the repair manual states.They run to the terminal board. I have a internal system with a two wire motor. I am reading the part in the book for all 1982-83 and CIM CIA CIB.<br />The throttle has the connection wires for the switch. Its not thru the wire harness. Question is where do the R B G wire go from the switch? and then where does the G B wire go from the pump. I think they are all going to meet on the <br />terminal board with the tan and yellow wires. I just can't follow the schmatic.<br />steve
