I'm in the process of transferring my right hand drive system from my 03 to my 09., I can't figure out which wire is the horn. The wiring is different in the 09, it has radio controls and Bluetooth along with the cruise on the steering wheel. Can't seem to find any answers online
I can only tell you with confidence that it isn't in the yellow harness, that's strictly the SRS system. If I recall correctly with older hondas, the horn wire is usually brown. You might be able to use a multimeter (with the car battery disconnected) to confirm continuity at the horn.
