25hp Yamaha 4 stroke cockpit oil light
I've a 2003 Yamaha outboard and an Avon Searider 4M with the 703 control box. I want to mount an oil light on the cockpit dashboard and later on a tacho.
I've got all the Yamaha manuals and wiring diagrams for the engine but still can't figure out how to wire in the oil lamp and tacho. There are 4 wires coming from the 703 control box; red, back, yellow and green. The red and black are kind of obvious but what about the yellow and green wires?
Any suggestions please?
