There the same system but the SST has longer range (up to 1 mile)
Did the install myself, i'v done quite a few,and I dont like others messing with my wiring. If you plan on doing it yourself I can post up the wiring for the truck. I also have a spare Passlock bypass module I'll let go cheap, you will need it if you want to do remote start also makes the door locks easy.
