Take 275mm Blue twin core screened cable, cut back the outer
insulation AND the screen braid to approx 25mm and insulate to
avoid fraying. Solder the White / Clear inner core to the
potentiometer terminal L3 and the Blue inner core to the
terminal L1.

Repeat for the Right channel, soldering the White / Clear inner
core to terminal R3 and the Blue inner core to terminal R1.

Take 200mm Blue twin core screened cable and cut back the outer
insulation to approx 25mm. Cut back the Blue inner core
insulation to 25mm, unplait the braid, twist these wires
together, and insulate. Solder these wires to the potentiometer
terminal L1, and the White / Clear inner core to the potentiometer
terminal L2.

Repeat for the Right channel, this time using approx 75mm cable.

Fit the potentiometer to the front panel using the washer and
nut provided. If necessary, scrape some paint away from inside
the chassis to make sure that the potentiometer is grounded.
