Yes that's right this is what I have. How do I wire the subset to the WE 203 and in turn how do i wire the subset to the phone jack?
Here are pictures. Thanks.

Welcom here, I do not recognize that phone with 6 cords to the subset.  I f you could point me to the schematics for the phone I guess I could help you, and I  am sure others here know more about that one.

I so you tape the Red from the dial, and the RR from the left hook switch on your picture. GN to GN. R to R. YY to L2 and Y to the capacitor wire terminal. If that subset not have a double capacitor you will need to add a 2-5uF nonon polarized capacitor between the YY and the Cterminal on the coil. Markings in the subset refers to coil.  It looks like you have a double capacitor, but I'm not sure.
