It goes over how to wire a crown ECU without the factory trans. I have a LS400/celsior ECU which is different of course, here is a pic of it

The LS400/celsior ECU has an extra 26 pin plug, and the loom has 3 additional plugs on it that plug into 3 receiving plugs inside the car. So has anyone used the article that Zuffen, KDog, 34FORD and The Giant Tomato helped to create, to wire a LS400/celsior ECU and get it to run without a factory trans? I am trying to get the engine to run in a non-lexus vehicle, without the factory trans. I have a running LS400 parts car that I pulled these parts off of. I'm going to try and work through this myself, but I would like to ask for help from anyone who has worked through this before, in hopes that it may save me time and money in alcohol.
