Connecting remote column to stereo

Ok so I got a new stereo after the last one got stolen...
I installed it and everything works well, good sound.
I'm wondering where do I find the connector to use the 19's steering column remote controls, which control the volume, the radio tuning, etc. If anyone's seen one, they know what I'm talking about, if not... I'll take a picture.

My radio is a Pioneer 2020 MP

Can anyone help me out with this before I give up and have to pay a car stereo specialist? :P

i have a random blue wire by my radio but it doesnt have a connector on the end and i hav no idea where it leads but the steering wheel control is the only thing i can think it leads to. worth noting that you need a compatible stereo anyways.
