FAQ Tab Highlight Custom Tab

[HM666]

Hi was wondering if this is possible to do. What I have done is I have a custom FAQ area with secondary FAQ questions & answers within it. I've created a link that is seen by only certain usergroups in the bottom part of the default navigation on vBulletin 4.2.3. The link only shows when a certain tab is clicked on the top part of the navigation. What I need is when I click that link in the bottom portion of the navbar is it possible to highlight my custom tab where that link shows instead of the "Forum" tab.

Basically the first screen shot is what you see before you click the top tab and go into the area I've highlighted the link to the custom FAQ area that I'm speaking of...

The second screen shot is what happens after you click the FAQ link. The tab that I have put a yellow highlight over is the one I want highlighted when you click that FAQ link from the first screen shot. Hope this is not too confusing.

I'm guessing that I need to create some sort of plugin, but I do not know what to put for the code.

EDIT: I also need that same top tab to stay highlighted when a member actually clicks on that particular forum area connected with that tab.
