Review on 🔌 Custom 4-Pin Trailer Wiring Harness, CURT 56120 Vehicle-Side Fits Ford Edge by Justin Ellingson

2011 Edge limited. Very easy installation, except for the subwoofer enclosure on the inside rear panel on the passenger side. Like many others, just cut this wire, run it down and down, then reconnect with a wire nut. I didn't power the battery either. I hooked it up to a 12 volt power supply (cigarette lighter adapter) located on the driver's side interior trim at the rear of the cargo area, which saved a lot of time. Got the fuse box fitted as pictured and the trailer lights don't use much power anyway so I don't expect any problems. After installation, I checked the functionality with a test lamp and everything is fine. Videos on YouTube are also a plus to watch beforehand.
