Trailer Wiring Harness for 1999 Lexus RX300

Question:

Hello Will this work for a 1999 Lexus RX300 ? If not why not. What is PWM , is that some kind of dimming thing ?

PWM stands for Pulse Width Modulation, which is a particular wiring system that some vehicles use. Instead of having a single wire for each different circuit, PWM will use the same wire for two or more circuits by using varying pulses for different functions. PWM is a fairly recent technology, your RX300 uses a more traditional wiring system.

The # 119190 converter you mentioned would work well for you, but I recommend the # 119190KIT that includes the wiring kit that includes the wire to connect to the battery, as well as the fuse holder and circuit tester.
