    Heater blower relay wiring question

    My heater and A/C blower is inoperable and I am trouble shooting the problem. One of the first problems may be the electrical connections. There are 4 wires that connect to the relay.
    The black wire(ground) has a connector attached and is seperated from the rest of the wires.
    The other three wires (orange,purple,green ) are supposed to attach with a three wire connector. My connector was destoryed and the wires were unplugged. I have obtained a replacement connector.
    The problem is I don't know what the proper sequence is for the wires. I have looked at the wiring diagram in the AIM but it is unclear as to how they are positioned. Can anyone check their relay and advise. It is starting to get cold here in New York so this has become a critical repair. I have a 70 350/300 with A/C.
    Thanks in advance.
