I removed the cowling from my 2005 Mercury 150 XR6 to troubleshoot another issue and when I went to replace it noticed these two wires. I'm guessing they should be connected based on their position and that maybe I snagged them when I removed the cover. However, they are very slightly different colors and I cannot find a wiring diagram anywhere. They closest I could find said that a brown wire went to a "trigger" which I don't know what that is.
