The other day I switched my Aladdin remote start from manual trans. mode to automatic so that I no longer have to do the "exit sequence". I tapped the neutral sensor wire at the ECU and connected it directly to the hood pin input, without using any type of diode system as the Aladdin uses voltage sensing not relays to drive the input triggers. It works great!
The only problem is now I don't get to see the confused looks on people's faces when I used to get out of my car with the engine running and then have the engine and headlights shut off magically.
