Attention all Grant Steering wheel installers!

[70c10]

I have posted a few times in the past about my Grant wheel install and my horn problem (battery draining). When I bought my truck it had a 91' S-10 factory wheel on it and the horn was not connected and didn't work. All I did was remove that wheel and install my new Grant. Here is the question: Do I need these factory parts in the pic attached to make the horn work correctly and prevent battery drain?. My horn works right now WITHOUT these parts BUT my battery dies. I'm thinking that little plastic insulator might be my problem. Did you guys REUSE these parts?. Thanks.........Jim
