I feel your pain man, I have the Innovate LC-1 and XD-16. Took me 2 weeks of troubleshooting the wiring. The wires coming off the gauges are so tiny that I'm scared to even touch them without breaking them. I called them and went on the forum for help, they all said i wired it wrong, which i know i didn't. It ended up being the stereo terminator plug that completes the daisy chain setup, i made my own while i waited for my new one to arrive. Other than the worthless instructions and horrible customer support i like the XD-16.
