Hello I will help you with your question,
The best solution for all the information that you need is to buy a one year, one vehicle subscription to AllDataDIY which will give you the wiring diagrams and the repair information for all those questions you haven't thought of yet.
You can get the diagrams piece by piece through me but it will save time and money to get a subscription for this vehicle
Let me know if you have further questions about this
Thank you
