Location of overdrive relay in right hand drive 1990 auto 240 sedan

[Jane Holder]

I'm having trouble locating the overdrive relay in a right hand drive 1990 auto 240 sedan. Lots of other forums say it is behind the glove box on the left, but this is for left hand drive vehicles. I can hear the clicking when I press the overdrive button, but can't really tell where it is coming from behind the dash. My overdrive isn't working and I've checked the fuse which is fine, so suspect it is the relay. Just need some tips on where it is likely to be so I'm not pulling apart the wrong part of the dash. Thanks
