help !!!!

[garyt]

Ok I need help with this one please, this is from a mk2 mx5 and lived , on a bracket, beside the boost sensor.
I've googled it and have conflicting answers !!!!
so what is it, what does it do and do I really need it?
If its to do with the egr then where do the 2 pipes go to and if its part of the evap then I don't need it.
Just worried that it has electrical socket and trying to avoid it triggering any fault codes if omitted.
Thanks in advance Gary
