Will this work on a 2019 jeep

If it has the 4 way flat you can or if jeep has pig for that purpose near the back bumper

What gauge wire is used?

It looks like it is about 18 gauge. A little lighter than I would have wanted. I wired it with a 20 amp fuse and have not had any problems with overheating wires. I am pulling a medium sized camping trailer with full lights, in-line brake controller, and 3 wireless cameras.

Will the lights work if I don’t use the brake wires?

Dear Rasa, Here is a video includes 3 detail wiring diagram of 'MECMO Multi-tow 4 Pin to 7 Way and 4 Flat Adapter'. Since it sounds like you don't need the brake output you can leave the additional connections disconnected. All you will need to do is plug in your existing 4-way to the 4-way plug on the adapter. Once this is done, the 7-way connector will have the functionality of your 4-way. However, if your towed vehicle equip with brake light, you will still need to splice the brake wire to keep all function works. Thank you MECMO Service Team
