Trim position gauge sensing wire color - Yamaha F150?

[nsimms]

Picked up a trim position gauge for the tilt/trim on my 2006 Yami F150. Can't seem to find a wiring schematic anywhere for this engine - can anyone tell me which of the wires leading to the Yamaha gauge plugs (which go nowhere on my boat - I have only analog gauges, not the Yami ones) is the one for sensing tilt position?

Thanks!

I know it's light green and sky blue @ the trim switch....

Thanks, Seaman. I need the trim position sensor wire color, as opposed to the trim/up down control wires. I found a file online with Yamaha wire colors listed, and it says it should be orange. But I don't know if that's current.

I've got a service manual on order and guess I will wait to see what that says. Don't want to toast a new gauge.

I assume trim position sensing is via a variation in resistance (a la a fuel level sensor)? I might try checking the resistance between the orange wire and ground as I raise and lower the trim while I'm awaiting the manual...

pink and black, which goes into the trim indicator, just looked it up on the wiring diagram

Thanks! I just picked up the service manual, and the wiring diagram does indeed show it's pink and black.
