Hi Lexus owners,
I am currently putting a pair of bucket seat from an SC430 into a an old muscle car and need to wire the seat for position control. There is a large connector with 2 large wires that must be for power. The wires are WHITE with a black stripe and the other is solid GREEN.
Any wiring diagram help to make these work would be greatly appreciated.

Thanks,
Dave

2003 seat wiring

This helps after the control box. I found that the blue-white wire is +12 volts and the white-black wire is ground. I got the seat to function except for the bottom elevation. I will check output to the elevator motor before looking at other issues.
Thanks for the diagram.

Dave I am doing the same project installing the seats in a 56 Chevy. I found the white black striped ground but can't find the blue striped wire. Can you share the location on drivers seat of blue stripped wire? Much appreciated, Thanks, Danny

How did you get the front and rear elevation to work. I'm having the same problem.

Hi,
I just saw your old post with the seat wiring diagram. What interests me is the software based manual for the 2003 SC430. What is it? Can it be bought?

How did you wire yours? I can't find the combo to wire anything but the lumbar support.

There should be a thin brown wire or a thin blue/red wire. That needs to be grounded.

the seats have connectors with plugs…the grounds are in the wire bundles.
what am I missing?

There is a large connector with 13 pins - may vary by year. Some of the pins are dummies; that is, there is no wire to that pin slot. The wires to the harness on the seat should be apparent (exposed), although you may have to peel back the electrical tape around the connector if the wires are hidden. You need to find the blue/white wire; that's the positive. If you have the male connector, trace that circuit and attach your power wire. Next, you need to find the white/black wire and the brown wire (some years, the brown wire is replaced by a blue/red wire). You need to ground BOTH of those wires. The blue/white and the white/black wires are larger than the other wires.
