Really you don't even need the module. I've seen people just hook up their parking lights straight to a 12v switched (like the one used to turn on your stereo)
Also, I did have a friend who used his foglights as his drl and passed his out of province(oop) inspection with it.(through the module so his foglights where basically always on whenever the key was in the ignition)
really the only thing the module will do is when the ebrake is engaged it will kill the drl(which is sometimes handy if your a stoner....) the modules are cheap 40$ and are very straight forward needing to be hooked up to 12v switched, ground, and tied in with the ebrake.
some vehicles are a bit more complex but for once we luck out and get away with something easy.
