hi everyone. Im new to this forum however i am a 2 time qx owner.I had 04 qx and towed my 7000lb camper with ease. I am looking for the plug for the trailer brake controller and not finding it on my 2011 qx. Is it the plug right next to the obd connector or elsewhere.also do i need a new harness or is the one from my 04 the same.Any help would be appreciated.
