I plan to install a mm style pickup on my latest custom creation. However, to be completely honest I don't know how to wire it. I plan to use this cheap pup for now beacuse I'm short on cash ( http://mailboxmusic.zoovy.com/product/BPU_MM4 ). the leads are mentioned on the page if you scole down a bit. i just don't know how to wire it or what and how many switches I need. any help would be apreciated. Thanks a bunch.
