I have a mars bill acceptor model ae2451u5. It came on a rowe dollar bill changer. I believe I have a bad bill acceptor, but i was wondering if anyone knows how many connectors is supposed to be hooked up to it and how many wires? It is a older changer that someone has converted to taking the new 5 dollar bills, and I am wondering if I am missing a harness, because when I hook up a different bill acceptor(one that takes old 5 dollar bills) using factory connectors it works. Please help!
