Weber 5F6A power transformer hookup

I just finished the Weber 5F6A kit and it sounds good, but........
I never could figure out the power transformer W022798 wires as per the
layout sheet. So I just wired them incoming AC black to fuse, fuse to power
switch, blue on other lug of power switch, and the white AC nuetral wire
nutted to black common transformer wire. The brown wire is not hooked up.
Green is grounded to chassis. My question, should I hook the brown wire to
the blue on the power switch also? The Weber 6G13A layout hooks the brown
and blue together on the power switch.
I know this might be a well worn question, but I couldn't find the subject
on dejanews.

Thank you.

From Weber Kit Info Page:
https://taweber.powweb . com /store/kitinfo.htm

The three wire power cord may be supplied in two different
configurations.

On both cables, green is earth and chassis ground.

On one type of power cord, brown is the hot lead and blue is the low
side.

On the other type of power cord, black is the hot lead and white is
the low side.

In all of our schematics, brown and blue are indicated.
Please check the colors of the power cord you received and wire it
accordingly.

You should use either the brown or the blue, but not both.
The end of the unused wire should insulated well to avoid
contact with anything else in the chassis.

The purpose for the two wires is to allow you to choose
between them depending upon your local line voltage. It
also allows you some change in B+ voltage, as using the
higher primary tap will net a lower B+, so long as the
line voltage is constant. If, using the 120V tap, you have
B+ of 450VDC, then, using the 125V tap should drop B+ to
around 430VDC.
