Last week I installed the trailer wiring harness (VPLMT0008) for $135 and it took under 5 minutes and the easiest thing to do. I read that the dealer would need to activate it...but that is incorrect. I called them and they said it's already active and the only thing they do is disable the back up sensors. So pretty much, it's a waste of labor. I can simply press the button to turn out the sensors. Installed the receiver and ball, picked up my trailer, plugged in the 4 pin adapter and lights came right on and tested everything. Picked up my boat and I'm a happy camper.

I had to have mine turned on at the dealer.
I did test it to make sure if it was working before I went to the dealer,
I got nothing,
after they enabled it then I had trailer lights.
Its quite possible some of these trucks had the towing system enabled at PDI at the dealer,
It looks like yours was done that way good for you!

Thanks for the advice to test first....my trailer adapter has a test light on it so when I plugged it in before I picked up the boat and trailer, it was red so I knew I was good to go with power...saved a few bucks!

My 2010 had a hitch without wiring installed when the 2nd owner bought it in 2012. When I installed the AB harness I had to go to my local indy shop to get it turned on, cost $50. I'll have to see if my newly purchased IIDTool will activate my 2011 when I get that done.

Kind of excited to see how 500HP does with towing my horse trailer, 375HP does it effortlessly now..
