Everything has a notch or something to keep a person from making a 
mistake.  Even the lcd power and on/off button lights and such have been 
made so you see the matching information on the pin and on the pin you 
attach to, so you just put like with like.  Even I seem to be able to 
follow the instructions.  I don't have a single concern about following 
the instructions properly.  They were stupid proof, perfect for me.
