Review on Street Guardian SGDCHW SG9663DC Hardwire by Norlan Pippinmd

A great addition to the SG9663DCPRO. In my opinion they should have been included with the purchase, but hey. FYI they come with very vague instructions. There really aren't any physical instructions, just an online manual (very vague). I had to look up youtube videos to learn how to install properly (prior to that I was unfamiliar with wiring on the machine). It's really easy if you watch a few videos. I deducted a star because I didn't have proper installation instructions/instructions.
