2005 Hayabusa K4/K54 (GPI) Gear position indicator wire location and signal decoding

[GeekOnBusa]

I am trying to add a GPI on my bike with a 7-segment display, for which I will use a microcontroller to decode the GPI signal and display it to a digit 7-segment display. I am doing this DIY because I can buy those things in India. The market is non-existent here and importing items from US/UK is a big headache because of customs duties.

However, I have no idea where the GPI wires are located, Some online forms say it looks like the one in the image below with a triangular wire.

Location given below

Question 1 : Is this the correct wire/ location? If so which wire carry GPI signal? is it blue wire?
Question 2 : The How to decode GPI sinal? Is it PWM signal? Or a variable voltage controlled by resistor array? Or something else? How to read it?

They show where it plugs in, which will show you which wires to use.
Or you can email them and ask for their gear position installation instructions.
