HEY guys i have a 2002 maxima and i have added a truck horn and a switch to control both the stock and truck horn together. The problem i am having is when i press the horn button on the steering wheel it doesn't work and there is power through the wire straight to the steering wheel and it has to correct voltage of power and i am concerned because when i press the horn i don't hear anything and im just worried what it could be.

Help please!!!!!

 

The horn is triggered off of a ground source on the wheel, not a power.
