Re: Lexus GS450H VCU Support Thread



I have updated the drawing after some remarks and updates found in the software.

Can you add this wiring diagram to the GS450H wiki? I don't think Damien has seen it listening to comments in his latest video.


Yes ofcourse!

Please find the latest version 2.4

Also the Download link to Visio ...

You want the 3 pins on the centre row as shown. The fat red wire is actually the Toyota blue wire covered in red heatshrink.

Re: Lexus GS450H VCU Support Thread


The pinout is in the post you quoted!

Black is PWM in from your controller.
Brown is feedback from the oil pump. Do what you want with this or leave it disconnected.
The fat blue wire is 12V power. The metal case is the ground.

Edit: I updated the wiki to include this.

Re: Lexus GS450H VCU Support Thread

Great feedback all!


This is great! One thing that sticks out to me immediately is the oil pump relay - if you're going to drive it from the VCU, I'm 99% certain it's going to be ground switched by the device, not power switched. Pin 15 should represent ground on the relay coil, not +12V. (Unless ...

Re: Lexus GS450H VCU Support Thread

To make it more clear, i have made a complete wiring diagram for the V2 board in visio.

As i am also missing the original wiring loom, unfortunately i can not check if all connections are correct.

I would really appreciate if everybody gives there remarks so i can modify and finalize the drawing ...
