Location of Trailer Running Light Fuse Under Hood of 2015 Ford F-350
Updated 07/25/2018 | Published 07/24/2018 >
Question:
I hope you can help me. I have a 2015 F-350 Super Duty Diesel and the running lights on the trailer are not working. I have connected the trailer to another vehicle and they work fine. Can you please point me to which fuse I need to check? The owner’s manual designates every trailer function EXCEPT for running lights. Thank you very much for your help!

I found an online diagram for the fuse box of your 2015 Ford F-350 and according to it the trailer running light fuse is in the 26 position and takes a 30 amp fuse. It's labeled as trailer tow park lamps which may be why it was harder to track down.
