'97 C/K1500 started the security system. Mostly Suburbans, but I have seen stripped W/Ts with it too. I have seen a few '97 trucks without it as well. Easy to tell - if there is a security light that comes on when the key is first turned on.
I've got 20+ years in remote starter installs. These trucks are cake to do if you know what you are doing. I leave the OEM keyless alone and install my system beside it. The only thing needed is the door lock wires at the keyless module above the gas pedal.
Very important thing to keep in mind on '95 up GM trucks when doing a remote starter install. There are two ignition wires that must be powered up during a remote start. The main is Pink and the 2nd ign wire is white. If the white wire is not powered up the tranny will go into a limp home mode after a remote start.
I use Crimestopper products because they work great, nice to install, and they are NOT DEI (Directed Electronics) products. Many years ago a Viper system was a decent system. I can't say so much for products manufactured in the last 10 or so years. Clifford used to be the best aftermarket security/remote starters by a long shot. Now they are owned by DEI and are just another garbage DEI product with Clifford's name. I just installed a DEI product in a 2005 C1500 for a guy last saturday. It was the biggest POS I have seen in a while. I know alot of people use them and have luck with them. I hate 'em. I typically install only my own products, but made a special concession for this customer. I have done alot of starters for them and his son sent him the DEI unit for xmas.
I have run a small side business for the last 15 years and have used Crimestopper products exclusively. I just sent in my first warranty return in 8 years (on something other than a remote) last week. It still worked, but was having trouble programming a replacement remote. It is also a 10 year old unit. I have had some other items go bad, but very few. Crimestopper is who told me the last item I sent in was 8 years ago. I do anywhere between 30-60 remote starters a season and have very little issues. I am one guy - I work a day job and hustle remote starters evenings/weekends to make a few extra bucks.
OP - if you are in or near Western PA, I'll take care of you. I stock the bypass module for most common vehicles. I always have 1 or more GM truck modules in stock.
