91 cutlass supreme what are these wires

My mom's car is a 91 Olds Cutlass Supreme, she's had some repetitive charging problems. She recently had an ignition module replaced.

Her car stereo now has so much static it's unusable.  I changed her battery today, and in the process found these two loose wires.  They are next to the sidewall by the battery.  The red (right) wire appears to come from beneath the fuel relay (the big black box in the foreground) and the second terminal on the left has a black wire and a tan or beige running to it, and disappears into a branch of the wiring harness directly below.

I'm 800 miles from home, if someone has an expanded wireing diagram and wouldn't mind looking them up for me, I'd appreciate it greatly.  If it's something I can take care of quickly while I'm here, I'd like to do so.  If they are pretty much no biggie, that'd be cool to know too. 

The car keeps popping the SES light, but she's had trouble getting the local mechanics she's used to find the issue. Just want to make sure these aren't part of the main problem.

Thanks for your time, guys!

They're clean, that's why I thought they may have been connected to something.  And sorry about the image - flashlight + PDA camera didn't make for a clear picture.

Thanks for taking time to respond.
