What are these connections?

Forum: 

Hi all, my first post! I bought a 1987 Toyota Blizzard LD21G. This vehicle was built by Daihatsu for Toyota and exclusively sold on the Japanese Domestic Market. The chassis/interior/frame is from a Daihatsu Fourtrak, but the engine is a Toyota 2LT Turbo Diesel.

With that said, there are a lot of unplugged things under the dash. Any Fourtrak owners out there know what these plugs are for? Can someone point me to a page in the manual?

There are three plugs:

1. Green cable and blue cable with brown dashes. The previous owner attached another connector to it and then spliced into it. That was connected to his radio...but I didn't look to see what it was.

2. Cable with a lot of wires and wrapped in black sleeve.

3. Red cable and red/white cable with blue dashes.

Ideas...? I feel like that should be plugged into *something* haha.
