## Questions & Answers

**Q: Will this work on a 2019 jeep**
A: If it has the 4 way flat you can or if jeep has pig for that purpose near the back bumper

**Q: What gauge wire is used?**
A: 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.

**Q: Will the lights work if I don’t use the brake wires?**
A: 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

**Q: is it durable ?**
A: Hi dear, MECMO trailer harness use only Amazon FBA which offers all customer free return and replacement. If you receive a defective product or the trailer adapter is under your expectation, you could return or ask for replacement through Amazon. It will be very convenience and does not charge you any fee for replacement in 30 days.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Really good plug for cheap!!!!!
*by K***E on March 29, 2025*

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!!

### ⭐⭐⭐⭐⭐ Great product
*by N***O on August 4, 2025*

Plug and play. Gotta buy some extra 12v wiring to run the trailer brakes to the brake controller, reverse bulb and ground. Supper solid would buy again.

### ⭐⭐⭐⭐⭐ Easy install
*by S***O on August 22, 2025*

Works perfect! Just what I needed for my jeep! I haven't hooked up a brake controller yet just needed for the light operation now.
