Do you have purple wire going to your heater fan, if so this could be a fan relay.

On a 74 that should be the high speed blower motor relay. Mounted on the HVAC box passenger side. Looks like there should be more wires though. Orange and purple are correct, but should also be a dark blue into that same plug. Then, a single black (ground) on a separate spade next to the plug.
