Question:
I have a 2003 F-150 XL, which does not have any trailer light attachments. I need the 7 way receptacle. What is my best option to go from no trailer wiring to a functional 7 way plug? Any help is much appreciated.

Expert Reply:
You will need to start with a 4-way (if you do not have one). For that you would want the # C56031.
From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
