Centre Display and ECU under handbrake cover

Hi all,

I’ve been stripping my car.

I’m wondering if I need the centre display on the dash. It displays the outside temp but I can’t remember if it does anything else like warning messages. Think they all come up on the dash clocks don’t they? My stereo is unplugged.

Also there is a large ecu under the handbrake / gear stick cover. A lot of people with track cars seem to have unplugged this. I think it’s for abs/traction control. There is a small connection which I have removed prob following advise on here to disable traction control but the larger connection is still plugged in. What does this box do and any effect from removing it?
 
Ok just seen a post from 2014 that confirms it’s the airbag ecu so good to remove that by the looks of it.
