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 # 119250KIT converter you mentioned would work well for you, it includes the wiring kit that includes the wire to connect to the battery, as well as the fuse holder and circuit tester. It also connects without splicing into the original wiring.
