I have two wiring harnesses that connect to nothing under my passenger side interior plate (where it usually has performance suspension badge) What are these two harnesses supposed to connect to? Any help would be greatly appreciated. I have an 87 Formula 350. Can anyone help me with this?

 

Sounds like where the computer and some relays are. Can you post a pic?

 

I know some camaros came with extra wiring for the bose system.

 

Could aLso be rear defog--got it? that's where the wring goes into the relay for it--pass side above your knees.

 

Power antenna also plugs in there.
