How do you ground a Fender Mustang?

[Snikch]

I’m beginning the process of wiring up a warmoth mustang guitar. The only wiring diagram I’ve managed to find for the electronics is this (see below)

The problem is, I dont know where am I meant to solder the other end of the ground wire? I assume its the one coming of the jack, but it appears to go nowhere. Now I’m quite new to the wiring of guitars, but even I’m pretty sure grounding is essential.

So, where should it go?

To the back of a pot. Stick all the ground wires to the back of a clean pot, volume, tone, you choose.

Ok cool. Thanks!

It's not shown on the diagram, but you should also have a wire connected to the bridge to ground the strings.  

The Warmoth body might already have a hole drilled from the bridge area to the control cavity.
