My New Gauge Cluster
http://www.usspeedo.com/clusters.html on the right side click the support button and under that they have install instruction (not for HHR) and install videos (again not for HHR) but I looked at the video and it shows it being done to a Cobalt. actually a slide show not video but it give you a very good idea how to do it and the HHR would be very close to the cobalt.
