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.
