under the hood, drivers side fender well, small brown canister with a screw on cap...take the cap off and it exposes about 8 female plug holes...the can has the male plugs.

I was told this is a computer port...but it is connected to the cruise control system and says VDO.

What is it?

What is suppose to do?
