In need of IAC help

So I have narrowed down my engines sporadic revving and stalling to the IAC. I just installed headers and some other mods so I assume it just needs to be adjusted, but I can't find the torx screw to do it. Any help or pictures would be great. I read the tech article on how to adjust it.

Torx screw is used to adjust the TPS not the IAC. IAC will adjust itself when you have the correct minimum air and correct TPS voltage.
