Where is the Ethanol sensor? 2007 Tahoe

[iamdub]

The ethanol sensor is up on the roof top directly in the middle. Its the size of a needle tip. You have to use a magnifying glass to locate it unless you have better than perfect vision. Make a youtube video of it and post links and when you find it, raise your hands in the air and say "By Jove I think ive found it!".

Pretty sure mine was contained within a 10mm socket.
