Place tenderloin in slow cooker. Combine 1 Tbl. soy sauce and next 5 ingredients (through garlic) and pour over pork. Cover and cook on LOW 4 hours or until tender enough to shred. Remove pork and place in a medium bowl, reserving cooking liquid. Let pork stand 10 minutes. Then shred with two forks.
Strain cooking liquid through a sieve into a bowl then return to slow cooker. Stir in remaining 3 Tbl. soy sauce, vinegar, and sesame oil. Cover and cook on HIGH 10 minutes.
Turn slow cooker off. Add in pork, cooked noodles, carrot, scallions, and cilantro, tossing to coat. Pour mixture into a large serving bowl. Sprinkle with peanuts and fresh cilantro. Serve with lime wedges.
