Installing Brake Controller

Hi,
   I plan on installing a prodogy brake controller on my 08 Equinox.  I am having a hard time finding specific instruction for this vech, I can only find a generic chevy install.  When I bought it it had a 4 pole wiring harness and hitch, does anyone know where I can find specific instructions or has anyone done it on there vech? 
 
Thanks,
Steve
