Door locks help 81/87 c10

I did some research on the door locks but I'm still confused. I have 3 wires on my door lock harness with a relay attached to the bracket on the pedal. I read that there is a wire or 2 that goes to the fuse box. I didn't see that wire on my 3 wire harness. How does the lock switch get it 12v. I'm a little confused. On a good note my windows work great with the relay mod. Any info is well appreciated
