Parts Needed to Install Curt Echo Under-Dash Wireless Controller on 2022 Lexus GX 460  


Im looking a the C27JR brake controller for my 2022 Lexus GX640 and I see it comes with a universal connector cable C51515. The Lexus comes with a factory installed plug for a brake controller. Does Curt make a specific cable for the C27JR that can plug into the factory brake controller plug? If it does, can you provide the model number? Thanks


Helpful Expert Reply:

To connect the Curt Echo Under-Dash Wireless Brake Controller # C27JR to your 2022 Lexus GX 460 you'll need the Pigtail # C51515 you referenced. It doesn't look like any of our manufacturers have a plug and play adapter and when I checked the online owner's manual I didn't see a port or wiring mentioned for trailer towing so I recommend verifying the plug you found carries the functions needed for the brake controller. You will connect the following functions to these wire colors on the pigtail:

Blue - 7-Way Output to Trailer
Black - 12V Power
White - Ground
Red - COLD Side of Stop Light Switch (only gets hot when brake pedal is pressed)
