Hey Guys, I am finishing up a customer build and need access to the wires that run to the ABS and Trac Module for the wheel speed sensors. I would prefer a pinout as I need the + and - sides of the wheel speed sensors. Any info? This is the last bit I need before we can start configuring the infinity on this GS300 turbo build. Will post some pics and info on this car as soon as I get it done.

Nobody has access to this info? I realize the manuals are copywriten and Lexus unlike Toyota locks down on their knowledge. But it takes a few min for someone who has the book or a pdf to tell me the wire color of the abs wheel speed sensors and maybe which pin they are in at the abs ecu. I need this for wiring in an infinity to a 99 gs300 and implementing the traction control. I really need this info, I have no access to it...

So far here's what I have: there are two shielded strands of wires from 2 different plugs on the ecu. Each has a red black and white wire then one has a yellow and the other has a green. Now I am familiar with the colors from working with our sc abs modules which we would wire for customer race cars (road racing). Now from there white is always a positive high side wire. Black is negative but never have I seen two blacks in a system. I'm guessing that's because it's a f/r difference? Problem is I don't know which is driven and what not. Still need that pinout...
