Oyviny 4 Pin Flat Y-Splitter Plug Adapter with 17.5 inch Trailer Extension Harness Plug and Play Adapter for LED Tailgate Light Bar and Trailer Lights Insulating Housing with Dust Cover

Nothing to say, just plug and play.

You can hook everything up all together

Will operate both sets of my lights just fine. I would hope they would beat-up the wire gauge, but in the long run - these should work fine.

It allows me to keep my truck bed lights connected and trailer/boat connected.

very nice product works great.
