2 accesory wires on ’03 mazda protege 5

ok i have an alarm that has one accessory wire and two ignition wires for remote start relay... problem the 02 year and the 03 maza protege 5's have the wires listed as :

02 blck/red as igntion #2

03 blck/rd as accessory #1

i know it makes a difference which wire is which but i cant check the wires b/c the blck/rd wire turns on only in the on position to me they would have 12 volts when u turn on the ignition only which is the same thing  but the two years are very close.

it is an -'03 mazda protege 5 so if the wiring diagram is right @

also visited www.bulldogsecurty.com and of course the 12volt.com but didnt have it

how would i hook up 2 accesory wires when i have only one accesory wire from the output from the remote/start alarm instead of an accesory 2 wire like most have ignition 1 and 2 wires...
