Upgraded the 2019 LX570 with a brake controller. I have a little M416 trailer with an upgraded Dexter axle with electric brakes. Yes I know a bit of over kill. I added the Tow Pro Elite brake controller using the plug-play harness and the switch blank plug. Wicked easy the hardest part was looking up other videos on how to pop apart the dash and finding the factory controller plug hiding behind the dash. Parts included the EBRH-ACCV3-NA controller, TPH-021 plug/play wire harness TPH-021, and the plug blank TPSI-002. Husky not included. I grounded the unit via a bolt framing the dash metal work.
