I'm building shelves into a closet and wanted to find the studs. I found an old Stanley intellisensor 77-110 stud finder but it is not working so I opened it up and found the red and black wires were not connected. I tried to figure out where they go but no luck. Are there any electronic nerds out there to help me out? I have a soldering kit already
TLDR: where do I attach positive and negative wires?

How did they come lose? They look like they go off to a speaker, but can't say. Did you strip the red wire?
Have you tried just a new battery? Flip the board over.
They look like they're for a speaker or more likely a buzzer - the bit that goes beep when you find a stud.
Check the casing, shit grade buzzers are usually glued or moulded into the plastic so that the wires rip off when someone pulls the thing open. Might be marked with polarity, probably wont be. Try it one way around then the other if it doesn't work.
Replace the battery.
I am not kidding, you can use an app to do that. Most phones have a good magnetic sensor for the compass.
