Adding a Buffer to another pedal

[Natman]

Hey all,
I decided to try a Barber B-buff in the battery compartment of my wah but I want to be able to switch it on/off. I think I can use a spst toggle but not quite sure where to place the buffer. I know it can go at the input jack but not quite sure of the right way to wire it in? Any help is appreciated especially if you can point me to a diagram! Thx

Have you considered contacting Barber?

They will install it for $20.00.
