Yeah.. The Yellow wire...

For the Antenna.. I would and DID pop a new hole in the firewall right beside where the hood latch cable goes through.. From there runs the cable up behind the trim going up to the roof..

One thing to keep in mind.. Plastic does NOT block reception for the sat signal.. If it's small enough you can even hid ethe actual antenna under the black trim.. I've got the same unit my wife does in her car with the antenna sitting ON her trunk deck and I still get fewer signal drops around town between buildings and under trees than she does...
