How to install this car alarm?

Question

I have installed 4 different alarms already and have never had a problem. Today i bought this alarm called CNSAC model: CD168-6C. In the diagram there are some wires that i have no idea what they mean. There are 4 wires that say are ch1, ch2, ch3, and ch4. What are they for?

Answer 1

 You seem to have no idea about wiring, and you intend to install an alarm in your car. I would advice you to seek a professional help, instead of landing in some pretty messy  trouble. Its a technical matter, and you cannot get detailed guidance through an online medium. Therefore its adviseable to have an expert assistance.

Answer 2

did you install the alarm? did you found out what does ch1, ch2, ch3, ch4 means? a think this might be a channel 1, 2, 3,4 but what kind of channels and for what?
