I just swapped out a late model larger hp engine on my boat. I kept the controls from the newer setup so that I could keep it as simple as possible. The harness plugs match, and I know where the large guage positive and ground wires go,but I have concerns about the four other wires that I see coming from the harness.The four wires are color coded as follows:tan,green/white,blue/white, and brown/white. The motor is all the way down and I can't energize the trim/tilt. I see a plastic screw on the port and starboard side of the mounting bracket but am not sure which to turn to try to bypass the trim and tilt and pull the motor up. I turned the starboard side plastic screw until hydraulic fluid came out and couldn't pull the motor up. Both screws are exposed on the mounting bracket. Any help on either issue would be greatly appreciated.....<br />Tony<br />
