Blower switch help - need the correct part number.

[43tutor]

I ordered a replacement NOS switch for my blower fan, part number #3431149. Car is a 72 Satellite Sebring Plus, with A/C. The new switch isn't the same as the old switch that I removed. New switch is a 4 position switch, appears to be Off, Low, Med, High. There are 4 leads coming out of the back for a plug-in connector. The old switch is a 3 position Low, Med, High. There are 3 wires connected to the back of the old switch. See photos below. Looks like I ordered the incorrect part, are there different switches for an car with or without A/C? If so, does anyone know the correct part number that I need?

All of those I was able to see had spade lugs for a connector or 4 wires (3 in one connector and 1 in another) or 4 soldered conductors with the same two plug arrangement. I did find these but they say for a C body. However, it looks like your old one and only has 3 conductors in one connector.
