I believe its a grounding issue behind he wheel.
Take it off and take a look at the contact that the red wire is using on the metal ring on the back side of that wheel hub. That is how it gets its ground, so it needs to be a great connection, and super clean. its two rings, one wire from below (brown/white) to the lower ring, and your red lead is connected to the upper ring. rich |

Just fitted momo adaptor and other aftermarket wheel,touch the horn wire to the wheel and all is load and clear. |
