These motors are not hard to build for the most part... Get a factory manual.. there a fellow selling electronic versions cheap on fleabay. Everything you need to know is in the manual and what's not is on this site somewhere...
You can check out my build project that I posted to get a quickie looksee on a motor build... it's posted
here
Main thing is don't be afraid to tear the motor apart, stay organized and just be paying attention to what came where... it's all pretty basic really. Good luck!
