Hagstrom Swede Wiring Diagram Here! | The Gear Page Aug 13, 2012Here's a wiring diagram for the switching part of the Hagstrom Swede. It's the only one I know of because I made it! The only other diagrams out there are schematics, so I put this together. Hope it comes in handy for you. Both switches are 3-way toggles but are slightly different.
