    In my G'ma unit in a 54 year old house the thermostat gave out after all those years.

    Ordered a A1-66 and it has leads extending from a sealed rear of unit.
    Two black leads and two blue leads.

    The old thermostat had screws on terminals , top screws are marked "line".
    Bottom wires are marked "load". They happen to have two extra wires tucked into the bottom screws, I would guess the wires go on to power another outlet.

    I dont know where to hook the black wires to or the blue wires.
    Hope the pics help.

    Judging by the condition of the conductors in the box (Image 1-15-19 @4:52 PM.jpg) You need to call a licensed electrician to look at the conductors. There appear to be serious burn marks and pits in the conductors. You are basically looing at a serious fire hazard,
