Hopefully it's an easy fix. As you say if it was a fuse I'd have some serious issues and to my knowledge so far there is very little wrong with the car.

Shame about the images being toast :(
Do the simple stuff first. Check the lamps and the wiring connections before assuming the switch itself is fubared.

was the st205 ecu also used as it would be looking for the chargecooler and if it cant see it that can throw up a light.
I have no idea to be honest. Is there any obvious difference between the Ecu's?
Define 'obvious' :)
There are several differences. If the ST205 engine swap didn't include the corresponding chargecooler there is a good reason for not using the Celica ECU.

This one?

If you're not living life on the edge, you're taking up too much room!

I have taken apart the rear panel, checked both bulbs and have checked all the connections which all looked okay. Thats why Im guessing the switch is In need of a good clean or replacement.

As I said above the warning light appears to have disappeared. It was something the previous owner said was a problem but since driving the car for the first time I haven't seen it once.
