Okay I am sure this is a dumb one and mindlesly simple but I can't get the horn button to engage on the 3 prong spring thing .
Any words of wisdom ?

 

maybe a dumb answere but puch and turn???

or you maybe already tried that

 

I fought with mine after installing a new wire. No matter how hard I pushed down on it and tried to twist the horn button on I couldn't get it to engage on the 3 tabs. I finally had to bend the 3 tabs up ever so slightly to get it to seat.

 

I got a new (probably Chinese) horn button for Christmas 2 years ago.

I had to actually shave part of the button off to get it to turn inside the wheel.

 

I have sworn to avoid violance but I will give it a try .

 

I have been contemplating this technique as well
