Wiper rocker switch wiring

1969 2+2 XKE, 4.2 Passenger Coupe Vin # 1R42907BW

Windshield wiper rocker switch wiring. My rocker switch has four terminal connections marked from the top end as you open the fuse panel 2, 4, 5, and 7 at the bottom. I have four wires colored Red/Green, Green, Yellow/Green, and Blue/Green. I have no idea which wire goes to which terminal. The wiring diagrams have do not have Blue/Green. Please advise?

Your thoughts would be appreciated.

When I cleaned up my instrument panel I made this diagram of wires. I show 4 wires going to my wiper switch.

I replied when you asked this on Wednesday:

Did that not answer the question?
