Remote Control 703

[KLCboatnut]

I just received a 1990 Yamaha 90 HP outboard. I have the remote control and harness to the motor however I do not have the rest of the harness that typically would go to the guages and alarms. The color coded wires comming out of the remote are : Green,Red,yellow,Black & Pink they form a pitail with one side having yellow and black that double back to the other side. Can someone tell me what color wires do what and what they opperate and also what the purpose of the double yellow and double black wires do or opperate?
Or where I can get a wiring schematic "diagram" preferrably free, I'm not cheap just broke
