90 accord alarm help
 

Hi, i was just wondering what engine cap and open dormer meant in the following attachment. Also, what does side door postive/negative mean? where would good placement be for the siren since my engine bay is very jam packed. Where is the ignition coil and brake switch wire? Should i hide the override button or does that not matter?
thanks for any help.
any good DIY guides even though its just connecting wires. if you were to make an "eye" when tapping into the wire. How would you go about doing that? strip 2 sides and how yould you get the insulation off?
