Oatse,

I would also like to know which wires are used. I have the factory service manuals and wiring harness data here....can you send me a copy of the instructions with the WR ecu? I will let you know what wires are used. ie MAF, O2, temp...

Also, it would be great for someone to document a install. I have been leaning to get the WR ecu and would like more information. Pics and steps listed on the board would boost sales through the roof!

ToyLexMods: beware of that Lexus shop manual! the wiring diagrams are COMPLETELY wrong for the SC400. A while back I was installing an SAFC (before I met the WR guys) and the harnesses' pin configurations didn't match at ALL. I asked the Lexus guys about it, and their reaction was that the diagrams were never much help, and that they traced wires using the color codes instead.

Madmax,

Thanks for the heads up. I always double check with the wire color code after initial search with the wiring diag.

I just wanted to confirm which wires the WR ecu tapped into. I will give Leo a PM.
