Coco's doc's are the best.
Good luck!
Also, if your able, take pics of your progress and send them in. That way we can help guide you through the process further..
Congrats on purchasing the TC, she's a real baby

With mine I added the switch in the "extra" hole.
Don't know how else to describe
Coco will answer, so never despair. Help is always here for you.
