Thanks to Joev I found it! I removed the passenger side front tire. I figured out the "plastic rivets" and removed the plastic liners. One goes over and in front of the wheel. The other is behind the wheel, between the wheel and the trunk area. Only the one between the wheel and trunk needs to be removed to access the AVAS, but, I was happy that I removed the one that goes over the wheel as it allowed me to run a wire from the AVAS over and behind that liner and into the passenger compartment. I put a switch right next to the trunk release lever. Now I can turn it off for testing purposes. IF you wanted to take the risk of just unplugging it for noise control I don't suggest just unplugging it. The plug has an o-ring that keeps the connections clean & dry. I don't see how taping it would keep the weather out. I spliced into the wire between the plug & the AVAS. I soldered and used quality heat shrink to make a water tight splice. This way only the wires on the AVAS is changed, not the wiring harness. Total time: one hour 15 minutes.
I can't tell if that photo that PV1 posted is it or not. I kind of looks like it, but I don't know what direction it's taken from. Now that I know where it is I can see most by looking of directly from the trunk. Looking straight down about 10 inches from the battery you can see hoses, wires and the side of the AVAS.
