Question:
I have a 2012 civic ex coupe 2 door. I purchased the tekonsha part 118240 I believe. It did not work. The brown and red connectors are different. What part number do I need?

Hey Adrian! The # 118420 is designed for the sedan models so that explains why it wouldn't work. The correct wiring harness for your 2012 Honda Civic Coupe EX is the # 118437. If you need anything else feel free to reach out in the comments below.
