How do I reattached my right speaker cable to the board?

I really think it's easier to pull the sound plug ins off the board than to remove the cable from them. It's really not built worth a %*$%. Fortunately there are three speakers, I've learned to live with only two. I state in writing to my customers that there is a 50% chance of this happening and that I'm not responsible for it before I start on one.

Just had this happen to me, it's quite frustrating as the connection looks identical in step 17 and then when you're putting it back together you realise that the connection isn't actually the same and I unfortunately don't have a hot air gun to hand.
