This was helpful, thanks mate.
Most would not be using the factory remotes as they would have broken. I have worked out the all the wiring. It was so annoying as I could not find any info anywhere. It seems Toyota don't even know about them, even though it has a Toyota part number on the box. I think this is only for Australian Celicas, the ST204R.
The whole loom for the alarm can be removed with one plug. This plug is in the LHS kick panel, the one closest to the door, bottom left of the first pic. In the background is the start cut relay.
After unplugging you need to get the 2 wires in the SOCKET you just unplugged from , the black and black/yellow in the corners of the plug, compare where they are in the white plug pic and join them together. These two are the start cut wires. DONT USE THE BK/YL IN THE MIDDLE OF PLUG, (it's ignition) . You are done! Of course you can remove the siren and bonnet switch in the engine bay too. Now follow the loom under the passenger side carpet, pull it all out including the black box (see pic below), switch and light in front of gearshift and the wire also keeps going to under the centre console to another connector which may have an ultrasonic detector.
