Any help you can provide is greatly appreciated. I am looking at having an astrostart (or similar item) installed in my wife's vehicles for christmas. I have access to a wholesale warehouse that I can purchase the equipment from, but I have no idea what I need to buy in terms of bypass, relays, etc. I have a guy lined up to install it, but he won't tell me what to buy because he wants me to buy it from him. I would obviously rather purchase the equipment at wholesale, and pay him the labor to install it! Anyway, any help you can provide me in what I need is really appreciated! The system will be for a 2002 Chevrolet Cavalier 4 door automatic. The vehicle does NOT have power windows or locks in it. Let me know if you need any other info. TIA!!
