how straight forward is the wiring portion of it? Do all these cars need to be coded after the instal? What other kits have everyone used? |
I have PDC and comfort access. W the OEM kit I did not have to touch thw external wiring for either. The trailer harness comes with wires and plug for CA that are superfluous on a 2011. Just install the trailer harness thru the second unused body pass thru. I did not have to move the PDC plug either. The only existing wiring I touched was
(1) relocate part of the PDC harness attached to the bumper cover to make space for the cut out
(2) splice into the backup light wire (P side), if your trailer has backup lights (mine does).
The cutout on the bumper can be very minimal, in which case you won't need the additional trim piece. As others suggest, if you angle the 7-pin receptive downward,it reduces the needed bumper cutout significantly.
Finally, I highly recommend the prodigy wireless ebrake controller. Much easier and more convenient than hacking your cup holder for the hard wired controller.
