Yamaha 25hp outboard wiring

[Simoncpr4]

Hi all,

I have a 2003 FT25BET and I'm mounting it on my Avon Searider SR4. I want to mount an oil light on the dashboard but can't work out from the Yamaha wiring if the oil pressure low signal comes from the CDI unit or not (the pink wire). Any ideas?

I also have a yellow and green wire that don't even feature in the wiring diagram. Any more ideas?

Installing a tach with warning lights will do what you want.

What model would that be?
