The flat box-like thing. top half is black, bottom half is silver with many silver stipples coming out. Has one plug heading into fan. I just found mine hanging by a wire under the air filter. Has 2 other ports for a plug to go into. And one of the ports is currently not connected to anything.
I vaguely remember disconnecting it to be able to reach the turbo better.

What does it do?
What does the 3rd port connect to?
Where does it mount to?

lol.... bad description, but maybe someone knows what i'm talking about.

 

its the fan control relay

ok makes sense.... i currently only have 2 plugs going into it, but it looks like there is a port for another one?
what else plugs into it? or does anything at all?

thanks guys

 

The Part's picture I see shows nothing going into it there.

 

That's your differentulator, totally useless part. Just kidding. Sorry I couldn't resist.
