injecting into admincp settings?

[Dr.CustUmz]

thanks squid, this is the hook I ended up using already =) but that hook, some option pages like turn site on off don't have that hook, and one of my products (didnt check every default settings page) actually has that hook 2ce so the stylesheet loads 2ce.

I tried using some js in the admin complete hook

$drcjQ = "<link ref=\"stylesheet\" href=\"style.css\">";

echo "<script>var headHTML = document.getElementsByTagName('head')[0].innerHTML;
headHTML    += '" . $drcjQ . "';
document.getElementsByTagName('head')[0].innerHTML = headHTML;</script>";

and even though it adds it to the head, it doesnt work =/

side note* I am out of iframes when im testing this, i open the options in a new tab and go to the settings of the product I'm working on.
example: yoursite.com/admincp/options.php?do=options&dogroup=onoff

so its the full page and no nav on the left or bar at the top

this is what I have currently working btw I'd just like to be able to get it working in the HEAD
