Yamaha repower gauge wiring

[LA_Champ]

I am repowering from a etec 225ho to a 2008 250 hpdi series 2. I have the 10 pin main engine harness and the 6y5-83553-no gauge harness. One end that hooks to the switch has a yellow, red, green and black wire. The other side has a yellow and a blue sorted together, 2 blacks and a green a little farther down the harness and a blue, yellow and red wire. I'm trying to hook up my analog gauges in the dash of my Champion boat. Does anyone know which wires go where? Thanks in advance!

yellow is key on 12V +, green is tach send,black is ground,the dark blue is for gauge lights.
hook the blue and yellow together and the lights come on with the key,or you can run the blue to your nav light switch.
red is constant 12v.
