I just did this on my DL650 last weekend, same issue. My power commander has the same plugs as the bike. I could get a hand on them from under the bike, but I ended up pulling the air box after much frustration. There is a tab on the bottom that needs to be pressed, then the plug needs to be pulled, that being said they don't just come off. I had to press the tab with one figure, then get another figure behind the plug and pull hard while pressing the tab. It's a pain but they will come off. Be careful of the wires, and don't use tools
