It is not just a switch. Contact the people that you bought the cruise control from for help installing. If they don't speak English, you probably are screwed.
Look in "new posts". You have so many different threads going, on same question. No worries, it'll settle down.
Basically you did a shotgun approach which is poor forum etiquette. I'm going to leave this one and delete the other posts you have. Ok you also did that with the reverse camera. Please do refrain from posting across multiple threads in the future. Answers get lost and people don't want to reply to multiple threads to the same question as it's not good use of their time.
