Hello my name is ***** ***** thank you for your question. This is not a Step by Step type of service. I can supply you with the rear lights wiring diagrams so you can use that to install your tow hitch wiring. Since the car did not come with one, this is strictly a custom install and there is no step by step for that. Can you read a wiring diagram?

I'll give it a try!

Ok, hang on while I give you the Tail light and Brake light wiring diagram

15 ft aluminum boat trailer with a 12.5 John boat.

That is the directionals. I take it you are doing a 4 pin tow harness?
