I decided to give it a try and just unsolder the blue wire on my TP2 adapter. Just in case it was the wrong one or there is a reason to use the blue wire later, I can always solder it back on. Plugged yellow to red and red to yellow. All good. No other software required. I was able to play movies with coreplayer without problems. Charging functions seems to be working normally, too. Tomorrow I shall try to hook up the video in my car while attaching the adapter to the car charger. I will post back if something is not working properly. Otherwise, happy modding.
