Best advice would be to familiarize yourself with the Installation Manual first. Don't rush, double check connections, test with 12V Test Light or Ohm meter before making ANY CONNECTIONS. Do one wire at a time and allow for bumps in the road. Lastly, before proceeding, do some stretching and bending because you will be bent in all kinds of positions as you install this item.
Like I said, I searched all over the net for a proper wiring diagram for my 2011 Aveo, most of the ignition switches were heavy gauge wire but mine was not.http://www.the12volt.com/installbay/...o_ignition.jpg this photo is of the heavy gauge type where all connections can be made under the dash. If you need pictures let me know.
