Electrical

I bought a remote starter for my '98 Altima. I have everything hooked up, which was difficult due to the two starter wires my car has. Everytime I use the remote start to start my car the alarm goes off. I found out that i need to hook a wire in my remote start to my alarm disarm wire in my car. i looked it up and it is supposed to be green with a yellow stripe, so i connected them and had the same problem...and here comes the question: The factory alarm disarm wire has a negative polarity, my remote start module shoots a negative pulse through the system to disarm the alarm so my car can start. The book said some cars may need a positive pulse, which requires the use of a relay. Since my alarm disarm wire is negative, does it require a negative or positive pulse to disarm it?

Thanks

help?
