I was wondering if anyone has installed their own autostart on an E46. I have done a couple on Hondas and Toyotas. Knowing that European cars are very different from Japanese cars, I want to know what I am getting into before I start. My 323ci has the factory remote entry and I want to leave that alone. I am only planning on adding the remote start feature. Is there anything in particular I should be aware of? I believe there's a chip in the key. So would I go about bypassing this the same way I would bypass a Toyota chip using the unit that holds an extra key in it? Also, is there anything I need to be aware of? Does anyone know the wire colors? Do I need to run the tach wire to the coil or is there a wire somewhere in the kick panel? Any help would be appreciated. THank you.
