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

Really good plug for cheap!!!!!

Seems to be good quality, the spring on the door flap is nice and tight, all the connectors are put on good and made it simple to install! Bolted right up to my bumper and fits really nice! Plugs into my 4 pin connector and bolt the ground to the frame, then all you have is 3 other wires to connect which if you know what you’re looking for makes install time quick! Definitely a great deal! Only paid $20 for the plug and saved more than that with the time it took to install it!!

A superior and professional mount for both 4-pin and 7-pin trailer electrical connectors

Very well made trailer connector, conveniently designed for both 4-pin and 7-pin trailer connectors. The instructions are clear and easy to follow. All mounting hardware included. Great to have both style connectors in one unit, for both light-duty and heavier trailers with brakes. I was especially impressed with the professional way the wires were wrapped against chafing. A great value for maximum flexibility.
