Question:
Had a short in trailer lights and blew fuse. Now running lights are powered all the time with lights turned off. Is there a fix for this or do I need to replace converter box.

If you haven't already, I would start by replacing that fuse. The # C56407 uses a 10 amp fuse. I'm assuming you repaired the short in the wiring as well so I would see if it works after the fuse is replaced. If it still doesn't work, it was probably damaged and should be replaced.
For a replacement on your 2018 Jeep JL Wrangler I would choose the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. When it comes to wiring we have found Tekonsha to be the most reliable option. The installation process will be the same as your old Curt wiring harness.
