Lights on

Worked well. I wish the done light allowed for a bit more amperage, so I could add a usb charging port

2018 F150 worked perfect

This was the easiest way to hook up the third brake light for truck bed cap.

T-harness

As advertised good quality fast shipping would definitely recommend this product

EZ, You betchya!

This 300200 wire harness worked perfectly on my 2020 F150 . Easy to install and the information was easy to understand. Wired the topper in about an hour. Took extra time because I wrapped the power wire from battery in a protective sheath prior to installation. I would recommend this to anyone installing a used topper.

Delivered really fast

I found this on a web search for solutions for the new F150 3rd brake light. I was a little skeptical since I'm out of state and hadn't heard of them but when I found out I could order it and pay through Amazon I figured it was worth a try. I got my order fast and EZ wheeler communication was excellent.
