If you ordered a kit with a 1590BB Enclosure option (larger enclosure)  there are a few considerations.

• The main consideration is that this enclosure although generally bigger than a 125B enclosure, has a more shallow depth.  That means that the jacks, in some ways, are actually a tighter fit in this enclosure.  For this reason, your kit may include "plastic enclosed" Switchcraft™ jacks rather than the "open metal" Switchcraft™ jacks that  are standard in all of our kits.
• The wiring should be about the same as the diagrams but may vary somewhat.  Make sure you size it all up before you start cutting hookup wire lengths.
