After battling the wire gremlins, I am starting over with the documentation and making sure that the connections match. Can you guys take a look and help verify? I will use this to rewire and verify everything. There may be mistakes, since I've been cutting and pasting from several sources (which may have been wrong). I've gone through and double-checked the info below. Let me know what ya think and maybe we can finalize it for others to use.
I have a same thread on Supramania... http://www.supramania.com/forums/showthread.php?t=59181
The info below has been updated with everything through post #5 of that thread on SM.
