I don't have access to the defogger wiring info for your vehicle, but I can help a bit with that. GM defogger switches and I think most others use a momentary pulse to activate a timer which runs for a certain length of time; I'm not sure of the exact time. I'm not aware of any place other than a repair manual where you could get the defogger wiring schematic. What I would suggest there is accessing the wiring to the defogger switch and testing the wiring. If you have a wire that shows 12V constantly when the defogger is turned on, the defogger timer is probably built into the switch. If a wire pulses 12v or ground when the switch is pushed, the timer is external to the switch and you will need to find the defogger power wire somewhere else. I would suggest using a relay to send 12v to the defogger wire whenever the accessory wire is powered up. Wire the relay as follows: 85 and 87 - 12v heavy gauge accessory output from relay bank, 86 - chassis ground(you may want to wire a toggle switch in here so that you can deactivate the defogger output in summer for example), 30 - positive defogger wire. If you have any more questions, feel free to ask. I sympathize with you about how they advertise a feature without giving info on how to make it work. I work at a DEI dealer and we sell the new Rattler 369D remote starts with a dedicated defogger output, and there's really no info on how to work that either.

I only work with the Python pieces, so I'm not sure which model the 554R is comparable to. I thought only the newer 56x series had the turbo timer and rear defogger options, but I could be wrong. I believe the 554R is still based on the old designs. I don't know of any wiring database that list rear defogger info. You need to test how the factory switch works or get a factory wiring guide. The output from the remote start triggers about 10 seconds after the vehicle is remote started. It can either be programmed to a latched output (stays on) or for a momentary pulse. If latched, it stays on for 5 minutes and then shuts down. If momentary, it will send the pulse again after 5 minutes to shut off the defogger. Turbo timer just requires you to hit two buttons (aux and *) before you exit the vehicles. It will then run for the programmed time (1, 3, 5 or 10 minutes) and then shut off.
