Yea, you THINK it was an ordeal.

Wait till the day the SKREEM, PTCM, RCM or other module acts up and the car wont start or run. Who are you going to get to diagnose the problem now?

My advice: You want remote start? FINE. Go buy a car with it engineered into the system so that the dealer and garages can go to ONE PLACE to find ALL of the service information. Tearing into a car's electrical system and doing mods on it is FINE if you are going to maintain it yourself - but to hand such a modded system to a shop and expect them to be able to proceed as if nothing had been done is a path to frustration and cost.

But, it's your car. I just make these remarks (now, read this carefully) as one who diagnosed, fixed, repaired and maintained complex electronics very similar to the modern (post 2000) automobile.

The purpose of my post is not to criticize or belittle your passion for your car. Why take a car that is KNOWN to be a total pain in the *** when the electrical system acts up - and add some poorly documented device to it? Of course, I work in electronics - the only electronics I saw for 30 years was the BROKEN electronics. Maybe you will luck out and never have an issue.
