That's fair. I'd consider myself fairly new to it all, I'm not passing judgment but it's worth checking out a vid on how to do... If you've used a soldering iron once or twice you could probably handle it.

You may also want to (or have your person doing the work) replace the single-shot resistor fuse with a self-healing one while they're in there. Both parts are on the controller board. The fuse is notorious for blowing, and that can make the whole system unable to detect your controllers.
