Boss429Dreamer 18 Report post Posted November 6, 2015 Hi guys, first post here. I'm replacing the rim blow switch in my wheel, and found out that the installed Flaming River tilt steering column is a one wire system. So just changing my switch will not fix the non-working horn. It was never hooked up in the first place (I bought the car this way). Just wondering if anyone has a similar system and how did you modify the steering wheel to work with the one wire? I assume a horn relay is required at a minimum. Quote Share this post Link to post Share on other sites
