I wanted to post these pics of the hands free sensor since I know what it looks like because I attempted to install the trailer hitch and new hands free sensor my self but pulling the rear bumper off stopped me.
PIC#1 Shows the actual old rear panel with the old sensor connected to the long plastic brace that needs to be replaced on top (that your dealer stayed with and is probably going to sell to someone who wants to upgrade their passport sport to hands free)
PIC#2 Shows the old brace and sensor with the 2 (30 inch) sensor cables that I pulled off the brace so you can get a better idea of what they look like(they actually look like the cable from your cable box) on top and the new brace that you have to cut about a 1/4 off with the new sensor and 8 inch cables on the bottom.I didn't get a chance to take pics of the new panel with the holes cut out for the tailer hitch or the short sensor but it looks just like the old one just with the shorter sensor cables.so your sensor area goes from about the whole length of that small bottom panel with out the hitch to about 8 inches to the right of the trailer hitch.
PIC#3 shows the old sensor on top and where the new one needed to be cut with the new sensor on the bottom.
I hope this helps everybody get a better understanding of how it looks and works,I always thought it was some kind of eye that worked the rear hands free.
