Connectors??

[ostrich]

Getting back to some wiring for my 85MCSS LS swap and cleaning up wiring and plugs under the dash. I have 4 connectors, not sure (actually can't remember) what they go to, or even if they were used. If you guys can take a look, any help appreciated.

Pic one and three look like the front speaker wires, pic two looks like the single white wire for tach .. the other plug looks like radio pwr/illumination

Thanks Kevin, forgot about the speaker wiring, have them out right now, no radio in it either.
