How do you repair the submarine on my sims agents

This was a tough one!
From the red wires: add wires vertically; then elbow right; connect to the wires already there; wires up; elbow right; connect to "T".
From solar panel just wire straight up to wires already there.

This will probably mess up what you thought was easy light and gear connections.

So here are the gear connections.
From generator: Put belt vertically on gear farthest left; connect with gear just above light eye - just below wire; gear to right; belt down and gear; gear to left; belt to the leftand gear; gear left; belt up and gear.

and light connections.
from first reflector: second reflector placed down below everything, reflecting left; third reflector level with eye reflecting right. AND YOUR DONE!
