Car Alarm ... need help

Car Alarm ... need help

I have this remote starter car alarm that I want to install in my corolla,...but the problem is..I would like to do it myself. cant afford installation...so I figure since I have the factory keyless entry system already on the car I think it should not be that hard to disconect the system and add the new alarm. My questions is...have somebody have done that? where is the main sensor of the keyless entry? if you have...give me detailed info..perhaps pics.

thanks....

well under the steering wheel is where the relay box is for the power doors. i dont have keyless so that is where i tapped into that system to have the alarm control that. as for the connection of the remote start, i suggest connecting the ignition wire to the 3rd piston from the left. i did it that way after following the book on 2nd and not being happy with the results.
