Somebody mentioned DOT 5 Silicone brake fluid. Don't use it! My recollection is that it was designed for DoD Jeeps that were stored in Europe, waiting for WWIII, and is not suitable for normal driving. I think vacuum brake fluid bleeding is the best way. There is risk in pumping the brakes to remove brake fluid, in that you are using a normally unused portion of the brake master cylinder and any rust of other problems with that section of the surface can cause failure of the seals. This happened to me several times with a previous car in the late 70's and early 80's.

I recently looked this up for somebody else. I think the "L" might stand for blue. I looked it up in my CD Service Manual. I don't understand the abreviations, but maybe this will help. For the "Heated Oxygen Sensor", Bank 1 Sensor 2: pin 1 color B? HT pin 2 color L-W? +B pin 3 color W? OX pin 4 color BR? E1 Air Fuel Ratio Sensor, Bank 1 sensor 1 pin 1 HAFR (right), color L? pin 2 color B-R? pin 3 AFR+ (right), color R? pin 4 AFR-, color G? Air Fuel Ratio Sensor, Bank 2 Sensor 1 pin 1 HAFL (left), color G? pin 2 color B-R? pin 3 AFL+, color L? pin 4 AFL-, color B-W?

If you contact Lexus, either on their web site or by their toll-free telephone number, I think they'll send you another one free.
