Negative battery cable is the easiest way for me too...the fuse thing for some reason did not work for me.
You best bet, is to find someone in tha CA forum that has a scaner in your area.
Get it scaned and find out waht to code is....If reseting the CEL by doing the fuse or battery removal, does not work and the CEl returns, get it scaned to see whats wrong.
