Factory Pioneer 6 disk w/ factory subwoofer

[Art Garcia]

Recently I installed the factory 6 disk pioneer stereo on my 01 sport trac. The stereo has three sockets in the back but my truck only has one plug. What are the other two sockets for? If I buy the factory subwoofer And plug the wiring harness to the socket on the passenger sidekick panel will the subwoofer work?

If the pins are in the sockets, it should work.....

The only pin that's in the radio socket is the main one which is ground,power,speakers etc.

Would I need another pin to go in the back of the radio or just that main one?
