I know there is an archive thread on this, But the thread is really old and the pictures are no longer there. So here is some decent quality pics I just had to figure this out on my own. I should have taken a picture before I dropped the transmission. (let this be a lesson to all you other 7 noobs out there take pics often Especially if someone has Jerry Rigged your car before). So here we go
1. Fat black wire is your positive from your battery when your starter is mounted connects to the terminal on the left hand side of the solenoid
2. On my car (looks like it was rigged) the red smaller wire connects to the left hand terminal of the solenoid
3. The thin darkgreen and yellow wire connects to the top blade terminal of the solenoid
4. The Battery negative cable Fat black with yellow stripe connect to either of the starter mounting bolts for a good ground for your car(or better yet relocate to the subframe and a new bolt with a clean wirebrushed surface)

Hope these pics help sorry I am no professional photographer

 

Good job so far, i've got an 84 gs with a 12a, and i have an extra wire next to the starter, it's blue if i remember correctly. I believe that i have read that is is supposed to be connected to the right most stud on the starter, but just wanted someone to confirm that placement.

Thanks!

 

I have an 84 gsl (thats what these pics are of) I havea wire that is just hanging closer to the side of the engine block not sure of the color though I have a couple things not plugged in im trying to figure out i got the car for free after all
