Review on 🔌 Tekonsha T-One® T-Connector 4-Way Flat Harness for Subaru B9 Tribeca, Forester, Legacy, Outback, Tribeca by Todd Cobb

I can't say how well it works as I haven't had it that long. However, the installation was clean and easy. The one for the Subaru Outback has a connector on one end and lots of 4 pin trailer wires on the other. The single plug has a built-in fuse. To install, I removed some interior panels and exposed the lamp socket. I hooked up the module to it, routed the wiring under the skin, and routed the trailer harness through the rubber plug in the boot liner. It is completely invisible and there are many cables that need to be connected to the trailer. I tied the harness to the hitch so it doesn't get in the way when not in use. A nice touch - the trailer plug comes with a cover to help keep the plug clean when not in use.
