Horn spring and pin

[BillOhio]

Hi guys.
I am having a turn signal issue and removed the steering wheel. I thought something came off that I now can't find and wondered if it was the pin. I looked at HBC and they have a spring and pin but says non wood wheels didn't use the pin?? Does the plastic end off the horn just push in the tube where the spring is and how far do you push it in?
Thanks!

Yes, just push spring in till top of nylon is flush with tube.

Great on the quick response Bentley

Thanks Bentley. Do I need to use the pin with a standard wheel?

I put this back together tonight without a pin. If it was there, I never saw it. Not sure mine went together right, I dont see what holds the plastic cap from the wires into the tube. Maybe there was a tab and that is what I thought left! 
So I have no pin and the horn seems to work fine.  Hopefully it doesnt start going off by itself this weekend.
