Comparing Trailer Wiring Harness Options for a 2009 BMW 3 Series

Question:

I am looking for a trailer wiring harness for 2019 BMW 328i 4-Door Sedan. Your website suggested: Curt 59496, Curt 59236, Tekonsha 119178KIT, Tekonsha 119179KIT, Tekonsha 119147KIT, Tekonsha 119190KIT. Is that correct? Be side the difference in MAX AMP for Stop/Turn and Tail Lights. What are the difference between them? I was told that Tekonsha 119147KIT is not compatible with 2009 BMW 328I Sedan.

The best trailer wiring harness option for a 2009 BMW 3 Series is the ZCI Circuit Protected Vehicle Wiring Harness part # 119250KIT since you don't have to splice but if you don't mind doing this you can save some money using the Vehicle Wiring Harness Kit part # C59496.

The main difference between the trailer wiring harness options for this vehicle are indeed amp ratings but also what comes with like a circuit tester etc and brand. They all do the same thing though in the end.
