How to Activate Trailer Lights on 2014 Jeep Grand Cherokee Laredo with C55515 Wiring Harness

Question:

2014 Jeep Grand Cherokee Laredo 4x4 I have read several of you posting on the fuse location to enable the trailer lights after installing C55515 trailer wiring harness. The last post I read for my Jeep did not match my fuse box numbers. Mine are: F28 - Trailer Tow Backup lights F29 - Trailer Tow Parking Lights F30- Trailer Tow Receptacle F53- Trailer Tow Left Turn/Stop F81- Trailer Tow Right Turn/Stop I have checked several of them and they appear to have fuses. The only ones I have not checked are F30 and F53. What fuse should I be focused on and will I need to have service update the cars computer to enable the trailer lights. I did install my hitch as well. If I need the cars computer updated how long does it take for the service tech to attach his scanner and update the computer? 2014 Jeep Grand Cherokee Laredo 4x4

I spoke with my contact at Curt and he said if you have installed the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C55515, you will not need to do anything with the fuses to enable the trailer lights. However, you will need to take your vehicle to your Jeep dealer and have them reprogram the Jeep's computer to activate the trailer wiring harness. It will take about 10 minutes.
