I would like to add autostart to my 04 Denali. I would like to be able if possible to keep the same remotes and use the existing alarm. Really more or less just want to add remote start to existing system. I would think there would be products that would use the existing system and require little or no actual splicing. Please let me know if anyone is aware of such a thing of any advice that might get me going in the right direction. Thanks so much!!!

yes thereare remotestarters that will add on to stock keyless systems. i would reccomend using a starter that has its own transmitters because range on stock systems are poor at best. all of your otions can be integrated into the remote starter as well as operating the factory security

Thing about add on remote starts and using factory remotes is that it has to deactivate your factory alarm to remote start. During remote start your factory system is disabled which means that a door can be opened and the factory alarm wont be triggered. Reason why this works this way is because if you dont deactivate the factory alarm before you remote start then the factory alarm will activate and the horn will go off. Rest assure that when the remote start sequence is over then the remote start will reactivate your alarm system. Not only that, but swerks makes a valid point by stating that the stock system transmitter range is poor at best(aftermarked has been proven to be far superior). If I were you then I would go to a true professional and have a alarm/remote start combo installed.

Swerks and Enice are absolutely correct. The other point is that the factory system will ned a dedicated output or aux output to drive i.e. swithc on the R/S by a spare button or combi thereof e.g. door unlock and trunk relase. I've yet to find one that has this.

Well you can press the lock button twice and connect your remote start input to the lock motor that provides 2 pulses to turn on but remember that the range is poor.

Makes perfect sense what you guys are saying...I guess using an aftermarker remote in the mix would give much better range. Thanks for the input. Do you guys think something like this would be a worth getting for the info and details I am looking for...would it provide more info than I find at say the wiring info found on this site???
First link is a cd on ebay...
Second link is the wiring info on this site.
I have put my share of alarms in but just want to make sure I have all the info needed to do it right the first time. I feel I could do it no problem with the right information. Stereo, alarm whatever it seems to be with this class 2 stuff sometimes there are special adapters and interfaces that are needed to do anything you want to do...Thanks for the rapid replies guys!!!

Get the GMSL2i. This is basically a box that has 2 input plugs. One receives power and grround while the other plug provides outputs like door triggers, lock, unlock and so on. All you have to do is connect the outputs of those wires to the matching wires from the alarm system/remote start. The only true connection you have to make to the vehicle is the Data wire which is connected at the OBDII connector and the power and ground. By the way you also have to connect your remote start harness which provides power to your ignition harness. Trust me, this should be a piece of cake and with that module makes it super easy. You can always PM me and I can help.

Another question please...
I have been researching the GM-SL2 and the SL2i...
One seems to be 1-way and the other 2-way data communications???
Which is my 2004 Denali???
1 way or 2???
Thanks

that has to do with the alarm system communication(a plug that connects directly from the alarm to the bypass module). I would go with DEI systems which are more installer friendly and sadly enough are widely availabe online. I've heard good things about compustar but my favorite for sure is the viper 5900 which is a 2 way model and is 1 mile range. Another note, compustars(i think) have that port for the 1 way or 2 way and you wouldn't have to match the wires anymore, the data is already going through one of the plugs but then again you have to get your hands on one and find out which port works with it. Good Luck
