I just picked up a DB7 as my project beater. Started stripping it down to install an alarm and my system then stumbled upon this part. Anyone know what this is? Its mounted behind the lower panel below the steering wheel and it has this blue button on it. Here is a pic of it.

 

Nevermind. Found out what it is. Mods please close thread. sorry.

 

It almost looks like a relay.

 

It looks to me like it's the button you use to reset the maintenance required light.

 

because that's what it is.
