Question:
I have a 2017 lexus rx 350. Planning on pulling a 1 axle trailer. Is 20 amp all I need for the brake controller and the battery line for a 7 way. Or do I need a bigger cb?

Expert Reply:
In regards to install a 7-way on a 2017 Lexus RX 350 like the Universal Installation Kit for Trailer Brake Controller part # ETBC7, you'd first need to start with the T-One Vehicle Wiring Harness part # 118252 which ish a confirmed fit as long as you have the factory tow package. In regard to the Universal Installation Kit for Trailer Brake Controller, the 20-amp circuit breaker would go on the brake output circuit and the 40-amp circuit would go on the battery charge line circuit.
For a brake controller, the Tekonsha Primus IQ Trailer Brake Controller part # TK90160 is a great option.
