GMC Sierra 1500 Forum : “remote starters.”

In my opinion, throw out the AutoStart kit, and just get your butt outside in the cold weather and start the truck yourself.  Those cheap remote starter kits always end up making a hackjob of the wiring system that your truck needs to start and run 24/7.  I've fixed wayy too many of those hackjobs to even want to put one of those anywhere near my 93 sierra.

But, if you still are lazy and don't want to go outside to start your truck in the cold weather, the haynes manual and the installation diagrams should be more than enough information for you to install the system yourself.  Just make sure to solder or crimp your wiring connections, electrical tape and zip tie them out of the way so moisture can't get into them and corrode your connections, and for god's sake don't hack it to save time, it will save you a lot of time and money in the long run if the system descides to fail and leave your truck dead, which it will.
