OK. You have the "SET" Toyota system. SET is a standalone subsidary of Toyota. We northerners do not have access to SET files. But, there is a way...
YOu need to remove the lower panel to expose the back side of the ignition cylinder. Here you will find a wire connector attached to the cylinder. Unplug it. Real close to thsi connector, you will find an identical connector. Plug this one onto the ignition switch. Follow the sube harness that is connected to the connector you unplugged. Working towards the driver side under the dash, unplug any connectors that are part of this harness. These other connector are identical to the factory harness. Just keep unplugging the subharness connections (where it interfaces with the factory harness)...As you unplug the subharness, plug the factory connection back to where they would go (there are not duplicates here, each connector is unique). Eventually you will come to a box. This is the controller. It, and the harness connected to it all needs to come out. There may be a wire hooked under the steering column; if so just undo the connection and remove the wire.
In short, there is a controller box and a sub harness. The sub harness plugs into the the existing factory harness in several places as it strings to the ignition switch. As long as you do each connector one at a time whilst removing the sub harness, and plug the factory connections back to where theyu go (the factory harness is really close to hwere it needs to be put after being disconnected form the sub harness, once you get the controller and sub harness disconnected, you should be OK. Some systems have a piezoelectric 'chirper' under the hood, a red and black wire. Just cut is and yank it tho the engine
compartment and pull it chirper out.
You will need to remove the lower finish panel from under the driver side of the dashboard before you can attempt any of this. Once you see what I am describing, it will not seem so foreign to you. It is just hard to tell you how to do it step by step...If we had the instructions, it would be a lot easier.
