Hello I just replaced my head gaskets on my 07 GXP. I had the heads sent off and done properly. I have little mechanical skills so bear with me. I'm putting everything back together and all is well so far. 1 minor snag. The throttle body has a port that I can't seem to find where or if anything attached to it. It's just underneath the brake booster line that runs from the throttle body housing to the booster Any info would be greatly appreciated. I have a picture but am new here and don't see where to attach it
