Hi
Does anyone know how to rewire the switching relay on my airconditioner. I bought a replacement part White Rodgers 90-380 and forgot the exact way the color wires are supposed to be on the prongs. I can't find anywhere a colored diagram of wires for that.
Please help if anyone out there knows this, I would be truly grateful

If it's not too late terminals 1 & 3 are the coil, 2 & 4 (high speed) are normally open, 2 & 5 (low speed) are normally closed.

Make and model numbers work wonders.
