The 18-year-old arrives after a two-year spell with Blackpool, where he reached the FA Youth Cup quarter final away to Chelsea.
Harrison scored 17 times last season in just over 20 appearances for the U18 side, as they finished second in the table and also tasted cup success.
The versatile winger will be eligible for tomorrow’s Pitching In Northern Premier League East Division clash at Stockton Town, subject to FA approval.
