Hello I will help you with your question,

The single wire is the heavy lead to the positive post of the battery. The two pin connector has a red and a brown wire. You might have to dig back in the harness to see the colors.

The small red wire runs to the positive post of the starter through a fuse link. The brown runs to the charge light.

Let me know how I can help

Thank you
