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 ### ⭐⭐⭐⭐⭐ Quick install and solid connections *by J***N on November 17, 2025* This adapter worked exactly the way I needed it to.
