Power Window Relay Harness Wire Gauge

I am going through the wire harnesses on my 1969 XR7. I wanted to know what the correct wire gauge was for both the Blue and Red PW Relay Harness. I currently have a light gray 10/12 AWG and a red 16/18 AWG. Not sure if this is correct.

Hi,
The red wire is 18ga, the blue wire is 10ga, and the black wire going to the 20amp CB is also 10ga
Cheers

Thank you Trixie, just found the diagram in the Osborne manual - the page was stuck!!!
