Review on Enhance Your Toyota Tundra with CURT 🚙 55378 Vehicle-Side Custom 4-Pin Trailer Wiring Harness in Black by Shawn Schmidt

is a similar product. This is exactly what I need to hook up trailer lights to my Tundra. I didn't get a factory coupler, but the front-to-back wiring is already there. You just have to snap 2 connectors and that's it! Took me 30 minutes (I read and re-read the instructions to be sure). The only thing I should note is that my 2002 Tundra has the connector on the driver's side, not the passenger's side (as described in the manual). Addendum: Doesn't work anymore after a few years. I found out at the worst possible moment: in the middle of the course, at night. My son followed me down the highway and called to say the lights were flickering. I thought it was trailer wiring but when we hooked them up to another tractor they worked fine. When I finally got a chance to look at Kurt's wiring harness, everything looked normal from the outside, so I'm assuming there's something loose somewhere inside?
