Remote Start

Has anyone added a after market remote start? If so, where did you get wiring diagrams? I am concerned about the security system. Any insight would be appreciated.

The installation info/wiring info should come with the product. The manufacturer may have a web site, that has installation info. They probably also have a tech link, if you have problems, you can call them or email.

I've never used a remote start.

Depending on the year of the vehicle, GM had a setup where, this system could be added, just plug and play.....of course, it was expensive....
