Question:
Hello. Hope you’re having a Good Friday. I have a 95 F350 I just bought the 4 flat connector for it and installed it. Which harness should I get so I can make it a 7 and 4 combo. Thank you have a great Friday.

Hello Jerry, thanks for getting in touch, and for your recent order. You can use the Universal Installation Kit # ETBC7 to upgrade your 4-flat connector to a 7 and 4 combo. This kit comes with everything you need to upgrade to a 7-way, including all of the necessary wires for an electric trailer brake controller. For that I recommend the Tekonsha P3 # 90195, since it is durable and easy to use. You can wire the controller using the included pigtail.
I have linked a few install videos below to provide you with some general instructions. Feel free to reach out if you have any questions.
