What Colours are positive on the power sub harness

[NC475]

Want to add a GPS connection to a new to me 2017 NC750XD. The bike came with a power outlet in the frunk. This outlet is connected to a Honda power sub harness. There is about 3 accessory connections, and the wires to them are all different colours. Does anyone know which colours are positive? Is it the right side or the left side that Honda always put the positive end on the connector?
Thank you, Kenny

Put a meter on it and see. Or consult the electrical schematic appropriate for your motorcycle year, model, and country market.

I found the exact answer I was looking for on a March 2018 post about auxiliary lights. The green wire is ground. Thank you to Superdedooperman. This forum is fantastic, so much information, just need to do some digging.
