08 silverado factory remote start

There won't be a (-) activation on the factory remote start; it's all done via data. Does the CAUGM perhaps have a data output which connects to the vehicle for that purpose as well as lock/unlock? Code Alarm doesn't show a manual for the CAUGM on their site, so I don't know more about it. If it has (-) outputs only for RS/keyless, you could probably use a 1701G to do what you need.
