my guess
My guess is that the wire in the first photo goes to the starter solenoid. You get some better light down there and clean up a little, you'll find a spade terminal on the back of the solenoid. Really, the wire already has a bend in it, and is so short, it couldn't go anywhere else.
The second pic, well, my coupe has Zeniths so I dunno.
Have you got a wiring diagram?
