Recommended Wiring For Brake Controller In 2007 Lexus GS430

Question:

Hi, I have a Tekonsha Primus IQ brake controller like your item # TK90160. Id like to move this controller into my Lexus GS430 2007 model. Is it possible for me to buy a loom with plugs to plug in under my dash? If not, can you sell just the plug and loom for me to wire it into my 2nd car? Many Thanks

There is not an adapter harness for your 2007 Lexus GS430. To hardwire this controller to your system you can use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127 to allow you to use the controller between two vehicles with the quick disconnect.

I don't see the wiring needed for your vehicle to use a brake controller, so you will need to do some custom wiring. If you don't have a 4-way flat connection, I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT along with the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 to give you the connections, circuit breakers, and wiring needed for a functioning 7-way with brake controller. I've attached videos to assist with this installation.
