Wiring
The Ground or Earth wire is a loose wire soldered to a pot on the scratch plate assembly (below you can see it in yellow)
This Ground wire should be threaded through the body via the hole inside the cavity as shown below left.
Turning the guitar body over, the Ground wire should be visible in the rear body cavity (above right)
The tinned end of this wire should be inserted into the small flap on the vibrato claw as shown in the photograph
To ensure a good connection, squeeze the flap down onto the Earth wire with some pliers.
Turning again to the front of the guitar, feed the signal connector (on the red/black wires from the scratch plate) through to the jack
cavity as shown below.
Push the signal connector from the scratch plate and the signal connector from the jack socket together.
Screw the jack socket into the jack cavity and carefully fit the scratch plate over the main cavity.
Making sure that no wires are trapped and that it fits properly over the cavity, screw the scratch plate to the body.
