You'll need to do three things:

1. Create a custom property:

   <Wix>
    <Product ...>
      <Property Id="SQLSERVER" /> ... 
    </Product>
   </Wix>
   

2. Add a custom dialog to your Wix UI to capture the user input and store it to a property. This tutorial should help you with that.

3. In the component that installs your web.config file, use the XmlFile element to update your web.config with the value of your property:

    <util:XmlFile Id="UpdateConnectionStringInConfigSection" File="[ROOT_DRIVE]inetpub/wwwroot/$(var.ProductName)/web.config" Action="setValue" ElementPath="/configuration/connectionStrings/add[\[]@name=&quot;ConnectionString&quot;[\]]/@connectionString" Value="[SQLSERVER]" Permanent="yes" />
