None of the 3 wires show 12 volts at the plug. white, yellow, black black seems to be the wire That shows most current. Also is there a video for this installation on HHR THANKS

The brake light switch on your 2009 Chevy HHR is impossible to find (as you've experienced) so you're going to need to actually install the Roadmaster Stop Light Switch Kit # RM-751428. You won't be needing to use the Brake Light Relay Kit # RM-88400 because your tail light wiring is combined and not separate.

I have attached an installation video of the stop light switch kit on a 2011 HHR that you can check out.
