Default Where is the ECU for the AHC on a 1999 Lexus LX 470?

I'm trying to disconnect the AHC electronic control unit and I don't know where it is. I'm aware of the two fuses that need to be removed to stop the blinking light.

Behind the center stack on the driver's side. You'll see 3 white-colored connectors that plug into the ECU.

Thanks hankinid . I don't know what you mean by the center stack but I assume it's under the hood. I'll look for it. 👌

The "center stack" is the area starting below the ash tray and ending at the top border of the touch screen. The ECU looks to be in the general area behind the 4-way flasher and transfer case locking switches. You'll need panel removal tools to get to it.

It's up relatively high in the drivers side footwell, inboard of the steering column.

Thanks for the response. I'm sure I'm going to replace the bladders and replace the correct hydraulic shocks when I can , but that flashing light is disturbing.
