I had my cruise control evaluated and was told that the Engagement switch interm. is failing and that I should replace. This job was priced at about $300 bucks, and I was wondering if it might be a little bit simple thing I could do, and what the part might cost?

 

I'm thinking this is the whole assembly that includes the blinker arm. I see it goes for just under a hundred bucks online, is this an easy changeout?
