Sorry for the noob question, but can someone post a picture of where the firewall factory hole is, i can't seem to find it and i managed today just to find a hose that was not plugged into anything today and find where it went, in the 3 hours i spent looking for the firewall hole
help please

 

If the hose is between the battery and the engine and the end is curved like the letter U, it is the transmission breather hose. It's not supposed to be connected to anything.
